Description

  The present invention relates to a switch suitable for operation of various devices mounted on a vehicle, and more particularly to a push-type switch that outputs a signal when a contact is connected by pressing a button, and a composite switch including the switch.

  2. Description of the Related Art In recent years, there are an increasing number of devices installed around a driver's seat of a vehicle, such as a car navigation device and a car audio device as well as a car air conditioner device. Along with this, the number of switches for operating the apparatus inevitably increases. These switches are generally installed on an instrument panel that can be reached by the driver. However, since the installation space is limited, it is necessary to efficiently lay out the switches on the panel. Moreover, when many switches are installed on the panel, it becomes difficult for the driver to operate these devices without error during operation.

  Therefore, as one of the solutions, use of a composite switch as disclosed in Patent Document 1 below can be cited. This composite switch has a structure in which a multi-directional slide switch is arranged below a push button, and a jog dial is arranged above and below the multi-directional slide switch so that a plurality of switches having different operation types are stacked and integrated. Therefore, if this switch is used, the number of switches installed on the panel can be reduced, and the space can be effectively used.

  By the way, for such a switch installed in the vehicle, in order to improve visibility during night driving, there is often provided illumination that illuminates the switch when the vehicle headlight is turned on. However, since this type of illumination is usually fixed on the instrument panel where the switch is installed, if a composite switch having the above-described laminated structure is installed on the instrument panel, the illumination is blocked by the components inside the switch. . For this reason, there exists a problem that the brightness | luminance of illumination falls and the visibility of a switch worsens.

  Further, when a plurality of switches having different operation forms such as the above composite switch are integrated into one switch, interference between the switches becomes a problem this time. In other words, a switch of another operation type may be mistakenly operated while a switch of a certain operation type is being operated. In this case, there is a risk that the apparatus may malfunction. Furthermore, when the number of switches to be integrated is large, the assemblability deteriorates, and there is a problem that the installation work on the vehicle becomes complicated.

When the dial knob is operated to slide, the contact of the dial switch is released, and the signal from the dial switch is not output even if the dial knob is rotated while being slid. It is characterized by.

  Further, in the composite switch having the above-described configuration, the present invention includes a slider that rotatably supports the dial knob, and that slides on the base around the mounting boss integrally with the dial knob. The dial switch contacts include an upper dial contact pattern fixed to the dial knob, a lower dial contact pattern fixed to the base, and an upper dial contact pattern and a lower dial contact pattern mounted on the slider. And a dial contact brush that contacts or separates from the slide contact pattern. The slide-type switch contacts include a slide contact pattern fixed to the base and a slide contact brush that is attached to the slider and contacts or separates from the slide contact pattern. And turn the dial knob When operated, the dial contact brush contacts the upper dial contact pattern and the lower dial contact pattern according to the rotation direction and rotation angle, and when the dial knob is slid, the slide contact brush according to the slide direction. It is possible to employ a configuration in which the dial contact brush contacts the slide contact pattern and the dial contact brush is separated from the lower dial contact pattern.

  Further, in the composite switch having the above-described configuration, the slide type switch may include an illumination unit that interlocks with the slide operation of the dial knob.

  According to another aspect of the present invention, there is provided a composite switch configured as described above, wherein the illumination unit includes an LED substrate having an LED lamp disposed on the substrate, and an LED contact fixed to the base.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an external view of a composite switch incorporating the push-type switch of the present invention, and FIG. 2 is a sectional view of the composite switch.

  As shown in FIG. 1, the composite switch SW of the present embodiment is applied as a switch for operating a car navigation device mounted on a vehicle. This switch integrates many switch functions by integrating the switch mechanisms of the three different operation types, push switch SW1, dial switch SW2, and slide switch SW3, which will be described below. The limited installation space can be used effectively.

  As shown in FIG. 2, the composite switch SW includes a housing formed by stacking upper and lower bases 11 and 12 on a vehicle-side panel 1 and covering a top case 13 thereon. A push switch SW1 is disposed at the center of the housing, and a dial switch SW2 and a slide switch SW3 are disposed around it.

  The housing also includes an illumination that lights up in conjunction with the driver's operation of lighting the vehicle headlight. As a result, the push type switch SW1 and the slide type switch SW3 shine during night driving, so that the switch has excellent visibility and operability.

  The push switch SW1 is a switch that switches between ON / OFF states by a pressing operation. In the car navigation device of this embodiment, this switch mechanism functions as a switch for determining an item selected on the display. That is, when the button 14 is pushed down with the finger (A), the button 14 is turned on, and when the finger is released, the button 14 returns to the original position and is turned off.

  The dial switch SW2 is a switch that outputs a signal by detecting either the forward or reverse rotation direction and its rotation angle by a rotating operation. In the car navigation device of the present embodiment, this switch mechanism functions as a switch for enlarging and reducing the map displayed on the display and adjusting the volume of the voice guidance. That is, when the dial knob 15 is grasped with a finger and rotated in the clockwise positive (B) direction in the figure, an independent signal is output at every predetermined angle. Further, when the dial knob 15 is rotated in the counterclockwise reverse (C) direction in the drawing, a signal in the opposite direction is output at every predetermined angle.

  The slide switch SW3 is a switch that detects a command in a target direction by a slide operation and outputs a signal. In the car navigation device of this embodiment, this switch mechanism functions as a switch for moving the cursor in the menu displayed on the display or scrolling the map in the target direction. That is, when the dial knob 15 is grabbed with a finger and is slid in all eight directions (front, rear, left, right, and diagonal) (D, E, F, G, H, J, K, L), a signal corresponding to the moving direction is obtained. When the finger is released, the dial knob 15 returns to the original position and switches to the OFF state.

  The above is the outline, but the feature of the composite switch SW of the present invention is that the brightness of the switch is increased to improve the visibility, the interference between the switches is prevented, and the assembly of the switch is further improved. It is in. Therefore, in the following, these three features will be described in detail together with the mechanism of each switch.

(1) Push-type switch FIG. 3 is a sectional view of the push-type switch, FIG. 4 is an exploded view of the switch, FIG. 5 is an operation explanatory view of the switch, and FIG. 6 is a circuit diagram of the switch. In order to facilitate understanding of the mechanism of the push-type switch in the drawing, parts not related to the switch are not shown.

  First, the structure of the push switch will be described.

  As shown in FIGS. 3 and 4, the push switch SW <b> 1 includes a button 14, an actuator 24, a click spring piece 25, a contact spring piece 32, a large-diameter coil spring 26, and a push contact pattern 31.

  The button 14 is a part to be pressed, and includes a button body 21 and a plate 22. The button body 21 is made of a transparent resin such as polycarbonate, and has a funnel shape including a hollow truncated cone-shaped operation portion 211 and a cylindrical shaft portion 212. A disk-shaped plate 22 made of a translucent resin such as acrylic is fixed to the operation portion 211, and a claw 213 is formed on the outer wall surface of the shaft portion 212. Further, the constricted portion of the button main body 21 is a light transmitting portion 214, and has a biconcave lens shape in which the center is thin on both sides and gradually becomes thicker toward the periphery. On the other hand, a cylindrical mounting boss 121 is erected at the center of the upper base 12, and a slit 122 is formed on a side surface of the boss. When the claw 213 is fitted in the slit 122, the button main body 21 is prevented from being detached from the upper base 12 and supported so as to be movable up and down, and the shaft portion 212 of the button main body comes into contact with the upper surface of the actuator 24.

  The actuator 24 includes a cylindrical body 241 and two arms 242, and a pair of claws 243 are formed on the outer wall surface of the body 241 corresponding to the arms 242. A substantially U-shaped click spring piece 25 is engaged with the claw 243a of one arm portion, and a substantially U-shaped contact spring piece 32 is engaged with the claw 243b of the other arm portion. A chevron 111 is formed on the inner wall surface of the lower base 11 facing the click spring piece 25.

  The large-diameter coil spring 26 is formed by winding a stainless steel wire in a coil shape, and is inserted into the body portion 241 of the actuator. The actuator 24 in which the large-diameter coil spring 26 is inserted is accommodated in the space between the lower base 11 and the upper base 12. As a result, the actuator 24 is constantly pressed against the bottom surface of the upper base 12 by the elasticity of the large-diameter coil spring 26.

  An LED lamp 2 for illumination is disposed at the center of the panel 1 on the vehicle side, and the LED lamp 2 emits light when the vehicle headlight is turned on. On the other hand, an opening 112 is provided at the center of the lower base 11 in accordance with the LED lamp 2. Further, the large-diameter coil spring 26, the actuator 24, and the button 14 arranged above the LED lamp 2 are all formed with a hollow portion penetrating the shaft center, and the button main body 21 constituting the button 14 and The plate 22 is made of a resin that transmits light.

  For this reason, the light from the LED lamp 2 is not blocked by the components inside the switch, and reaches the outside through the cavity. At this time, the light that has passed through the light transmitting portion 214 from the LED lamp 2 is refracted by the curved surface of the biconcave lens, the beam diameter is enlarged, and diffused inside the operation portion 211. Therefore, when the headlight is turned on, the light of the LED lamp 2 is irradiated over a wide range of the plate 22 and the entire plate 22 shines brightly. Therefore, the visibility of the button 14 is excellent even during night driving.

  Next, the contact structure of the push switch will be described.

  As shown in FIG. 4, the contacts of the push-type switch are configured to include a push contact pattern 31 and a contact spring piece 32.

  The push contact pattern 31 is fixed to the lower base 11. A vertical wall portion 113 is provided at the center of the lower base 11, and a pair of contacts 311 of the push contact pattern 31 are embedded in the inner wall surface thereof. The pair of contacts 311 correspond to the sixth contact and the seventh contact shown in FIG.

  The contact spring piece 32 is attached to the actuator 24. A contact spring piece 32 is attached to one arm portion 242 of the actuator, and the tip of the contact spring piece 32 is bifurcated to have two contact portions 321. The two contact portions 321 come into contact with or are separated from the sixth contact and the seventh contact of the push contact pattern 31.

  The above is the structure of the push-type switch. The operation will be described below.

  In the no-load state shown in FIG. 3, the actuator 24 and the button 14 placed thereon are biased upward by the elasticity of the large-diameter coil spring 26. When the button 14 is pushed downward from this state, the push switch SW1 becomes as shown in FIG. That is, the shaft portion 212 of the button main body presses the arm portion 242 of the actuator downward by the pushing operation, and the actuator 24 receiving the pressing force descends against the elasticity of the large-diameter coil spring 26.

  Here, the click spring piece 25 attached to the actuator 24 is bent and deformed inward when the mountain-shaped protrusion 111 of the lower base is climbed, and after the ride, the click spring piece 25 is elastically restored by its own elasticity. At this time, a click feeling when the button 14 is pushed in is obtained by the resistance force received by the click spring piece 25.

  Further, the contact spring piece 32 attached to the actuator 24 moves downward while sliding on the inner wall surface of the lower base 11. Finally, the two contact portions 321 of the contact spring piece 32 simultaneously contact the sixth contact and the seventh contact of the push contact pattern 31. Accordingly, since the sixth contact and the seventh contact are connected via the contact spring piece 32 in the push contact pattern 31, both the contacts shown in FIG. 6 are conducted and the switch is turned on.

  On the other hand, when the finger that has been pressing the button 14 is released, the push switch SW1 returns to the original state shown in FIG. That is, the large-diameter coil spring 26 is released from the pressing force and is elastically restored by its own elasticity. At this time, since the actuator 24 is pressed upward, the actuator 24 that has received the pressing force moves up until it abuts against the bottom surface of the upper base 12. As a result, the contact spring piece 32 rises while sliding on the inner wall surface of the lower base 11, and leaves the push contact pattern 31. Accordingly, since the connection between the sixth contact and the seventh contact is disconnected in the push contact pattern 31, both the contacts shown in FIG. 6 become non-conductive, and the switch is switched to the OFF state.

  During the operation of the push switch SW1, the large-diameter coil spring 26, the actuator 24, and the button 14 are all configured to move up and down in the axial direction of the switch. The light path is not obstructed and the brightness of the illumination is not reduced.

(2) Dial type switch FIG. 7 is a sectional view of the dial type switch, FIG. 8 is an exploded view of the switch, FIGS. 9 to 12 are explanatory diagrams of parts, FIG. 13 is an explanatory diagram of the operation of the switch, and FIG. It is a circuit diagram of a switch. In order to facilitate understanding of the mechanism of the dial type switch in the drawing, parts not related to the switch are not shown.

  First, the structure of the dial type switch will be described.

  As shown in FIGS. 7 and 8, the dial switch SW <b> 2 includes a dial knob 15, a slider 44, a cover 45, a torsion spring 46, and a rotor 47.

  The dial knob 15 is a part that rotates, and includes a dial 41, a knob 42, and a grip 43.

  The dial 41 has a cylindrical shaft portion 411 and a flange portion 412 extending at the lower end thereof. A number of gears 413, 413,... Corresponding to the number of clicks are formed on the entire outer wall surface of the shaft portion 411 (see FIG. 9).

  The knob 42 has a cylindrical shaft portion 421 that fits into the dial 41 and a flange portion 422 that extends to the upper end thereof. The inner wall surface of the shaft portion of the knob 42 is fixed in close contact with the outer wall surface of the shaft portion of the dial 41. Further, a hole 423 for mounting the grip 43 is formed on the side surface of the flange portion of the knob 42.

  The grip 43 is provided to make it easy to grasp the dial knob 15 and has an annular portion 431 that covers the flange portion 422 of the knob. A claw 432 is formed inside the annular portion 431. The grip 43 is attached to the knob 42 by covering the knob 42 over the knob 42 and locking the claw 432 in the hole 423. In this manner, the dial knob 15 is configured by integrating the three components of the dial 41, the knob 42, and the grip 43.

  The slider 44 is a component for rotatably supporting the dial knob 15 in this dial switch, and includes a cylindrical body 441 and four legs 442. An annular recess 443 is provided on the outer periphery of the body portion 441, and a claw 444 for mounting the cover 45 is formed on the side surface thereof. Then, the dial 41 is inserted into the concave portion 443 of the slider. As a result, the dial knob 15 rotates around the body 441 in the recess 443 of the slider.

  The cover 45 covers the slider recess 443 and has an annular top plate 451. The top plate 451 is provided with an attachment piece 452 that covers the side surface of the slider 44, and a hole 453 corresponding to the claw 444 of the slider is formed there. The cover 45 is mounted on the slider 44 by covering the slider 44 with the cover 45 and locking the claw 444 in the hole 453.

  A torsion spring 46 and a rotor 47 are attached to the cover 45. The torsion spring 46 has a shape in which a stainless steel wire is wound in a coil shape and both ends of the torsion spring 46 are widened like ridges. As shown in FIG. 10, when the cover 45 is viewed from the back side, the top plate 451 of the cover is provided with a pin 454 and a pair of hooks 455. First, the pin 454 is inserted into the coil of the torsion spring 46, and then the hook. 455 is hooked in a state where the flange portion of the torsion spring 46 is sunk inside. Further, one end of the torsion spring 46 is bent upward, and its tip is inserted into the shaft hole of the rotor 47 and fixed. As a result, when the dial 41 is viewed from the upper surface side as shown in FIG. 11, the rotor 47 is always pressed by the elasticity of the torsion spring 46 so as to mesh with the gear 413 of the dial.

  Next, the contact structure of the dial type switch will be described.

  As shown in FIG. 12, the contact point of the dial type switch includes dial contact patterns 51, 52, a first dial contact brush 53, and a second dial contact brush 54 which are divided into two upper and lower stages.

  The upper dial contact pattern 51 is fixed to the dial knob 15 (see FIG. 9). An annular groove 414 is formed on the bottom surface of the flange portion of the dial 41, and the upper dial contact pattern 51 is embedded in this groove. The upper dial contact pattern 51 is formed by arranging contacts on three concentric circles having different diameters. On the innermost side, a second common contact 511 is formed which has contacts on the entire circumference. An eighth contact 512 and a fifth contact 513 are provided on the outside thereof. The eighth contact 512 and the fifth contact 513 have contacts and insulation portions alternately arranged in the circumferential direction, and are shifted in phase by a predetermined angle.

  The lower dial contact pattern 52 is fixed to the upper base 12. As shown in FIG. 12, when the upper base 12 is viewed from the upper surface, eight circular openings are formed in the circumferential direction, and among these circular openings, the lower three openings are adjacent to the front. The contact of the dial contact pattern 52 is exposed. The contacts of the lower dial contact pattern 52 are a second common contact 521, an eighth contact 522, and a fifth contact 523. Although these contacts are all on the same circumference, the second common contact 521 is disposed at an inclination of 45 degrees to the left in the figure, whereas the eighth contact 522 and the fifth contact 523 are the second common contact 521. In the drawing, it is inclined at an angle of 45 degrees to the right. Note that regions on both sides of the contact are insulating portions.

  The first dial contact brush 53 and the second dial contact brush 54 are attached to the slider 44. As shown in FIG. 12, when the slider 44 is viewed from the back side, a first dial contact brush 53 and a second dial contact brush 54 are attached. The slider 44 has pins protruding around two adjacent leg portions, and the pins are inserted into the mounting holes of the respective brushes and welded. As a result, the first dial contact brush 53 and the second dial contact brush 54 are fixed to the slider 44.

  The first dial contact brush 53 is composed of two leaf springs, and these leaf springs have an upper contact portion 531 that is warped upward and a lower contact portion 532 that is warped downward. . The upper contact portion 531 of the first dial contact brush is arranged on two inner and outer concentric circles having different diameters, and the upper contact portion on the inner circle side and the upper contact portion on the outer circle side are both from a window 445 opened in the slider 44. Projecting into the recess 443.

  The second dial contact brush 54 is composed of one leaf spring. This leaf spring also has an upper contact portion 541 that is warped upward and a lower contact portion 542 that is warped downward. The upper contact portion 541 of the second dial contact brush also protrudes into the recess 443 from the window 445 opened in the slider 44.

  Then, the first dial contact brush 53 and the second dial contact brush 54 mounted on the slider 44 contact the upper dial contact pattern 51 fixed to the dial 41 and the lower dial contact pattern 52 fixed to the upper base 12. Alternatively, they are separated.

  For the first dial contact brush 53, the upper contact portion on the inner circle side is the eighth contact 512 of the upper dial contact pattern, the lower contact portion of the inner circle side is the eighth contact 522 of the lower dial contact pattern, and the outer circle side The upper contact portion of the upper dial contact pattern is disposed opposite to the fifth contact 513 of the upper dial contact pattern, and the lower contact portion of the outer circle side is disposed opposite to the fifth contact 523 of the lower dial contact pattern.

  As for the second dial contact brush 54, the upper contact portion 541 is disposed opposite to the second common contact 511 of the upper dial contact pattern, and the lower contact portion 542 is opposed to the second common contact 521 of the lower dial contact pattern. Yes.

  The above is the structure of the dial switch. The operation will be described below.

  In the unloaded state shown in FIG. 7, the rotor 47 is urged against the gear of the dial 41 by the elasticity of the torsion spring 46. When the dial knob 15 is grabbed and rotated in the positive (B) direction from this state, when the rotor 47 gets over the teeth of the gear 413, it is pushed outward against the elasticity of the torsion spring 46, and after getting over the torsion spring 46 It is pushed back between teeth by the elasticity of. At this time, when the dial knob 15 is rotated by the resistance force that the gear 413 receives from the rotor 47, a click feeling can be obtained by a predetermined angle.

  As shown in FIG. 13, during this rotation operation, the slider 44 does not move on the lower base 11, whereas the dial 41 rotates around the body 441 of the slider. Accordingly, the relationship between the brush and the pattern is as follows.

<Relationship between first dial contact brush and upper dial contact pattern>
Since the slider 44 does not move, the first dial contact brush 53 also does not move, and the positions of the upper contact portion 531a on the inner circle side and the upper contact portion 531b on the outer circle side of the first dial contact brush do not change. On the other hand, since the dial 41 rotates, the upper dial contact pattern 51 also rotates, so that the eighth contact 512 of the upper dial contact pattern is on the upper contact portion 531a on the inner circle side, and the fifth contact 513 is the upper contact on the outer circle side. Contact and separation are repeated alternately with respect to the portion 531b.

<Relationship between second dial contact brush and upper dial contact pattern>
Since the slider 44 does not move, the second dial contact brush 54 does not move, and the position of the upper contact portion 541 of the second dial contact brush does not change. On the other hand, since the dial 41 rotates, the upper dial contact pattern 51 also rotates, and the second common contact 511 of the upper dial contact pattern moves while being in contact with the upper contact portion 541.

<Relationship between first dial contact brush and lower dial contact pattern>
Since the slider 44 does not move, the first dial contact brush 53 also does not move, and the position of the lower contact portion 532 of the first dial contact brush does not change. In contrast, since the upper base 12 does not move, the lower dial contact pattern 52 also does not move, and the eighth contact 522 and the fifth contact 523 of the lower dial contact pattern remain in contact with the lower contact portion 532, respectively.

<Relationship between second dial contact brush and lower dial contact pattern>
Since the slider 44 does not move, the second dial contact brush 54 does not move, and the position of the lower contact portion 542 of the second dial contact brush does not change. On the other hand, since the upper base 12 does not move, the lower dial contact pattern 52 also does not move, and the second common contact 521 of the lower dial contact pattern remains in contact with the lower contact portion 542.

  The circuit output by this operation will be described. As shown in FIG. 14, the ON / OFF state is alternately switched at predetermined intervals between the eighth contact and the second common contact. Then, the ON / OFF state is alternately switched between the fifth contact and the second common contact with a delay of 1/4 pulse. Therefore, independent signals are output at the click stable points for each predetermined angle.

  On the other hand, when the dial knob 15 is rotated in the reverse (C) direction, the ON / OFF state is switched alternately between the fifth contact and the second common contact first. The ON / OFF state is alternately switched between the eighth contact and the second common contact with a delay of ¼ pulse. Therefore, an independent signal different from that in the positive direction is output.

  In this slide type switch, the slider 44 is integrated with the dial knob 15 to slide in the target direction. A click pin 61 and a small-diameter coil spring 62 are attached to the slider 44.

  The click pin 61 is formed by forming a hemispherical pin 612 at the tip of a cylindrical shaft portion 611, and the shaft portion 611 is inserted into the coil of the small diameter coil spring 62. Further, the click pin 61 and the small diameter coil spring 62 are attached to only one leg portion of the four leg portions of the slider 44. A hemispherical recess 114 is formed on the lower base 11 facing the click pin 61, and a pin 612 at the tip of the click pin is fitted in the recess 114. As a result, the slider 44 sandwiched between the top case 13 and the lower base 11 is constantly pressed against the concave portion 114 of the lower base by the elasticity of the small diameter coil spring 62.

  The garter spring 63 is a component for holding the slider 44 in a fixed position, and is formed by winding a stainless steel wire in a coil shape to form a spring and connecting the whole spring in a closed loop shape. As shown in FIG. 17, the garter spring 63 is fixed by being hooked on holding plates 124 erected at the four corners of the upper base 12. Further, the four leg portions 442 of the slider are in contact with the inner side of the garter spring 63.

  The guide 64 is a component that guides the slider 44 in the target direction. As shown in FIG. 18, the guide 64 is composed of two parallel lower rails 641 and two parallel upper rails 642 perpendicular thereto, and the upper rails 642 are stacked on the lower rails 641 in a lattice shape. It is the structure joined together. The upper rail 642 is fitted in parallel horizontal grooves 446 formed on the bottom surface of the slider 44, while the lower rail 641 is fitted in parallel vertical grooves 123 formed on the upper surface of the upper base 12. Here, the direction of the upper base 12 is shown rotated by 90 degrees for the purpose of explaining the structure. On the contrary, a vertical groove may be formed in the slider 44 and a horizontal groove may be formed in the upper base 12.

  The direction 65 is for displaying the operation direction of the dial knob 15, and includes an annular display portion 651 and a cylindrical shaft portion 652. The display unit 651 is formed with eight indicators 653 that indicate the sliding direction of the dial knob 15. Only the portions of these indicators 653 are exposed with transparent resin, and the other portions are painted with a dark color. . A step 654 is formed on the inner wall surface of the shaft portion 652, and the direction 65 is fixed to the slider 44 by fitting the slider body 441 into the step 654.

  The LED board 66 is illumination exclusively for the slide switch SW3 provided separately from the illumination of the push switch SW1. The board 661 is provided with LED lamps 662 on both sides of the board 661 corresponding to the positions where the eight indicators 653 are formed, and these LED lamps 662 all emit light when the vehicle headlight is turned on. . The LED substrate 66 is fixed to the back side of the direction 65.

  The connector 67 is a component that connects the LED substrate 66 and the LED contact brush 74. A contact pattern 671 is embedded in the connector 67, and the contact pattern 671 is exposed on the inner wall surface of the connector 67. Further, the connector 67 is provided with a pin 672, and the contact pattern 671 and the LED lamp 662 are electrically connected in advance by fitting the pin 672 to the LED substrate 66 and joining with the solder 673.

  On the other hand, a notch surface 447 is provided on the body portion of the slider 44. The LED contact brush 74 is attached to the slider 44, and a leaf spring piece 75 is integrated with the LED contact brush 74, and a bent portion 751 is formed by bending the center of the leaf spring piece 75 at a right angle. It protrudes from the through hole 448 in the notch surface. A notch surface 655 is also provided in the shaft portion of the direction 65, and the connector 67 disposed on the notch surface 655 is fitted to the notch surface 447 of the slider.

  Therefore, when the direction 65 is put on the slider 44, the connector 67 presses the bent portion 751 to bend and deform the leaf spring piece 75 inward, whereby the direction 65 is attached to the slider 44. At this time, since the contact pattern 671 contacts the leaf spring piece 75, the LED lamp 662 and the LED contact brush 74 are electrically connected via the connector 67.

  As described above, in this embodiment, the wiring of the LED board 66 is completed by a simple operation of simply attaching the direction 65 to the slider 44. For this reason, it is not necessary to perform troublesome wiring work for illumination, and the assembly of the switch is greatly improved. In particular, the direction 65 and the slider 44 are provided with notched surfaces at corresponding positions, so that they can be mounted in the correct orientation by abutting both the notched surfaces.

  Next, the contact structure of the slide switch will be described.

  As shown in FIG. 18, the contact point of the slide type switch includes a slide contact pattern 71, an LED contact pattern 72, a slide contact brush 73, and an LED contact brush 74.

  The slide contact pattern 71 is fixed to the upper base 12. As shown in FIG. 18, when the upper base 12 is viewed from the upper surface, eight circular openings are formed in the circumferential direction, and the upper base 12 slides from three adjacent openings at the rear of the circular openings. The contacts of the contact pattern 71 are exposed. The contacts of the slide contact pattern 71 are a first common contact 711, a first contact 712, a second contact 713, a third contact 714, and a fourth contact 715.

  In the first common contact 711, the center in the circular opening is an insulating portion, and the periphery thereof is a contact. In the first contact 712 and the second contact 713, an insulating part is provided from the center in the circular opening to the left and right regions, and the first contact 712 is disposed rearward and the second contact 713 is disposed forward. In the third contact 714 and the fourth contact 715, an insulating portion is provided from the center in the circular opening to the front and rear regions, and the third contact 714 is disposed on the right side and the fourth contact 715 is disposed on the left side.

  The LED contact pattern 72 is also fixed to the upper base 12. That is, the contact of the LED contact pattern 72 is exposed from the left two openings of the circular opening of the upper base 12. The contacts of the LED contact pattern 72 are an LED plus contact 721 and an LED minus contact 722. Note that, in the LED plus contact 721 and the LED minus contact 722, the entire area within the circular opening is a contact.

  The slide contact brush 73 and the LED contact brush 74 are attached to the slider 44. As shown in FIG. 18, when the slider 44 is viewed from the back side, a slide contact brush 73 and an LED contact brush 74 are attached. The slider 44 has pins protruding around the remaining two legs 442, and the pins are inserted into the mounting holes of the respective brushes and welded. As a result, the slide contact brush 73 and the LED contact brush 74 are fixed to the slider 44.

  The sliding contact brush 73 is formed by integrating three leaf springs, and each of the leaf springs has a contact portion 731 that is warped downward. All the contact portions 731 of the slide contact brush are arranged on the same circumference.

  The LED contact brush 74 is composed of two leaf springs. These leaf springs also have contact portions 741 that are warped downward. The contact portion 741 of the LED contact brush is disposed on the same circumference as the contact portion 731 of the slide contact brush.

  The slide contact brush 73 is arranged to face the slide contact pattern 71, and the LED contact brush 74 is arranged to face the LED contact pattern 72. With respect to the slide contact brush 73, three contact portions 731 correspond to the first common contact 711, the first and second contacts 712, 713, and the third and fourth contacts 714, 715 of the slide contact pattern 71. Is arranged. Further, with respect to the LED contact brush 74, two contact portions 741 are arranged at positions corresponding to the LED plus contact 721 and the LED minus contact 722 of the LED contact pattern 72.

  The above is the structure of the slide switch, and the operation thereof will be described below.

  In the no-load state shown in FIG. 15, the slider 44 is biased to the lower base recess 114 by the elasticity of the small-diameter coil spring 62. Further, as shown in FIG. 17, the leg portion 442 of the slider is pressed inward from the four directions by the elasticity of the garter spring 63, and the slider 44 remains at the center position on the lower base 11. This is the fixed position of the slide switch SW3.

  When the dial knob 15 at this fixed position is held and operated in the forward (D) direction, the slider 44 accommodating the dial knob 15 also tries to move simultaneously. At this time, the same forward force as that of the dial knob 15 acts on the slider 44, but this force is a force in a direction perpendicular to the upper rail of the guide 64. For this reason, the horizontal groove 446 of the slider functions as a stopper, and the upper rail 642 of the guide is sealed from moving in the front-rear direction. On the other hand, since the lower rail 641 of the guide is free to move in the front-rear direction, it is guided by the upper base longitudinal groove 123 and slides forward. That is, the dial knob 15, the slider 44, and the guide 64 are integrally moved horizontally on the upper base 12 in the forward direction. Since the same applies when the dial knob 15 is operated in the rear (E) direction, the description is omitted here. This is the principle of the sliding operation in the front-rear direction.

  On the other hand, when the dial knob 15 at the fixed position is operated in the left (F) direction, a leftward force is applied to the slider 44. This force is a force perpendicular to the lower rail 641 of the guide. is there. Therefore, this time, the vertical groove 123 on the upper base functions as a stopper, and the lower rail 641 of the guide is blocked from moving in the left-right direction. On the other hand, the lateral groove 446 of the slider is free to move in the left-right direction, so that it is guided by the upper rail 642 of the guide and slides to the left. In other words, the guide 64 stops on the spot, and the dial knob 15 and the slider 44 are integrally moved horizontally on the guide 64 in the left direction. Since the same applies when the dial knob 15 is operated in the right (G) direction, the description thereof is omitted here. This is the principle of the sliding operation in the left-right direction.

  Furthermore, the sliding switch SW3 can also perform an oblique sliding operation by combining the above-described longitudinal sliding operation and the lateral sliding operation. For example, when the dial knob 15 at a fixed position is operated in the diagonally forward left (H) direction, the force acting on the slider 44 is applied to the left-side force component orthogonal to the lower rail 641 of the guide and to the upper rail 642. And are distributed in the orthogonal force component in the forward direction. For this reason, the horizontal groove 446 of the slider is guided to the upper rail 642 of the guide by the former force component and slides to the left. At the same time, the lower rail 641 of the guide is guided to the vertical groove 123 of the upper base by the latter force component. To slide forward. That is, the dial knob 15, the slider 44, and the guide 64 are integrally moved horizontally on the upper base 12 in the diagonally forward left direction. Note that the same applies when the dial knob 15 is operated in other oblique (J, K, L) directions, and the description thereof is omitted here. As described above, it can be slid in any one of the eight directions that are oblique to the front, rear, left, and right.

  When the dial knob 15 is operated from a fixed position in the target direction, for example, in the right (G) direction as shown in FIG. 19, the click pin 61 mounted on the slider 44 rises against the elasticity of the small-diameter coil spring 62, and the lower stage Pull out from the recess 114 of the base. At this time, as shown in FIG. 19, the slider 44 moves in the right direction, so the right leg of the four legs presses the garter spring 63 and pushes it outward against the elasticity.

  On the other hand, when the finger operating the dial knob 15 is released, the slide switch SW3 returns to the home position shown in FIG. That is, the garter spring 63 is released from the pressing force of the slider 44 and is elastically restored by its own elasticity. At this time, since the slider 44 is pressed inward, the slider 44 receiving the pressing force moves to the left. Further, when the leg portion of the slider 44 comes on the lower base concave portion 114, the click pin shaft portion 611 is pushed down by the elastic force of the small diameter coil spring 62, and the pin 612 is accommodated in the concave portion 114. In this way, a click feeling when the dial knob 15 is slid is obtained by the resistance force received from the lower base 11 when the click pin 61 enters and exits the recess 114.

  During the slide operation, the dial knob 15 and the slider 44 move horizontally on the lower base 11 as described above. At this time, the relationship between the brush and the pattern is as follows.

<Relationship between slide contact brush and slide contact pattern>
In the fixed position, the slider 44 does not move, so the slide contact brush 73 does not move, and the three contact portions 731,... Are in contact with the insulating portion at the center of the slide contact pattern 71.

  Here, when the dial knob 15 is operated in the diagonally forward (J) direction to the right, the slide contact brush 73 moves in the same direction simultaneously with the slider 44, so that the three contact portions 731,. Move diagonally forward. At this time, as shown in FIG. 20, the contact portions 731,... Make contact with the three contacts of the first common contact 711, the second contact 713, and the third contact 714.

  On the other hand, when the dial knob 15 is operated in the diagonally backward right (L) direction, the slide contact brush 73 moves in the same direction simultaneously with the slider 44, so that the three contact portions 731,. Move diagonally right backward. At this time, as shown in FIG. 20, the contact portions 731,... Are in contact with the three contacts of the first common contact 711, the first contact 712, and the third contact 714.

  The circuit output by this operation is as shown in FIG. When the dial knob 15 is operated obliquely forward to the right, the three contact portions 731 of the slide contact brush 73 are in contact with the first common contact 711, the second contact 713, and the third contact 714. As a result, the second contact 713 and the third contact 714 are connected via the slide contact brush 73 in the slide contact pattern 71. Therefore, both the contacts are turned on and turned on, and an electrical signal corresponding to the diagonally forward right direction is output.

  Further, when the dial knob 15 is operated obliquely rearward to the right, the three contact portions 731 of the slide contact brush 73 are in contact with the first common contact 711, the first contact 712, and the third contact 714. Thereby, in the slide contact pattern 71, the first contact 712 and the third contact 714 are connected via the slide contact brush 73. Therefore, both the contacts are turned on and turned on, and an electrical signal corresponding to the diagonally rearward right direction is output.

  Briefly describing other directions, the second contact 713 is in the forward (D) direction, the first contact 712 is in the rear (E) direction, and the fourth contact 715 is in the left (F) direction. The third contact 714 is in the right (G) direction, the second contact 713 and the fourth contact 715 are in the diagonally forward left (H) direction, and the first contact 712 and the fourth contact are in the diagonally backward left (K) direction. 715 is turned on, and an independent electrical signal is output.

<Relationship between LED contact brush and LED contact pattern>
At the fixed position, since the slider 44 does not move, the LED contact brush 74 does not move, and the two contact portions 741 are in contact with the contacts 721 and 722 at the center of the LED contact pattern 72.

  Here, when the dial knob 15 is operated in the diagonally forward right (J) direction, the LED contact brush 74 moves in the same direction simultaneously with the slider 44, so the two contact portions 741 are diagonally forward right from the center of the LED contact pattern 72. Move in the direction. At this time, as shown in FIG. 20, the contact portion 741 moves while being in contact with the contact in both the LED plus contact 721 and the LED minus contact 722.

  On the other hand, when the dial knob 15 is operated in the diagonally rearward (L) direction, the LED contact brush 74 also moves in the same direction simultaneously with the slider 44, so that the two contact portions 741 are tilted to the right from the center of the LED contact pattern 72. Move backward. At this time, as shown in FIG. 20, the contact portion 741 moves while being in contact with the contact in both the LED plus contact 721 and the LED minus contact 722.

  As described above, when the relationship between the LED contact brush 74 and the LED contact pattern 72 is seen, the two LED contact brushes 74 can be used regardless of whether the dial knob 15 is in a fixed position or operated in the target direction. The contact portion 741 maintains a state in which both the LED plus contact 721 and the LED minus contact 722 are in contact. That is, the LED plus contact 721 and the LED minus contact 722 are always connected via the LED contact brush 74. Therefore, power is supplied to the LED lamp 662 from the leaf spring piece 75 integrated with the LED contact brush 74 via the contact pattern 671, so that the LED lamp 662 is caused to emit light regardless of whether the dial knob 15 is operated. be able to.

  Further, when the dial knob 15 is operated, the direction 65 also moves in the same direction. However, since the LED board 66 is fixed to the direction 65, the direction of the dial knob 15 is interlocked. For this reason, the light from the LED lamp 662 is not blocked by the components inside the switch, and always illuminates the direction 65 evenly from the back side. Therefore, when the headlight is turned on, the light of the LED lamp 662 is directly irradiated to the direction indicator 653, and the luminance does not decrease. Therefore, since the operation direction of the dial knob 15 is displayed in an easy-to-see manner even during night driving, there is an effect that the operability of the switch is excellent.

  Finally, the relationship between the slide type switch and the dial type switch will be described.

  The composite switch SW of the present embodiment is configured such that even if the dial knob 15 is accidentally rotated simultaneously when the dial knob 15 is slid, the contact of the dial switch SW2 is separated and no signal is output. ing.

  As shown in FIG. 20, the contacts of the dial type switch SW <b> 2 are the upper dial contact pattern 51 fixed to the dial knob 15, the lower dial contact pattern 52 fixed to the upper base 12, and the first attached to the slider 44. 1 dial contact brush 53 and second dial contact brush 54. The contacts of the slide switch SW3 are a slide contact pattern 71 fixed to the upper base 12 and a slide contact brush 73 attached to the slider 44.

  Here, when the dial knob 15 is rotated, the upper dial contact pattern 51 rotates, so that the contact repeats contact and separation with respect to the upper contact portion 531 of the first dial contact brush, while the second dial contact brush 54. The upper contact portion 541 is kept in contact. At this time, the lower contact portion of the first dial contact brush 53 is in contact with the fifth contact 523 and the eighth contact 522 of the lower dial contact pattern, and the lower contact portion of the second dial contact brush 54 is the second common of the lower dial contact pattern. It is in contact with the contact 521. As a result, the fifth contact 523 and the eighth contact 522 are switched while the second common contact 521 is conductive, and a signal is output from the dial switch SW2.

  On the other hand, as shown in FIG. 20, when the dial knob 15 is slid to the right diagonally forward direction, for example, the slide contact brush 73 moves to the diagonally forward right direction, and the contact portion 731 has the first common contact 711, the first The second contact 713 and the third contact 714 are contacted. As a result, the second contact 713 and the third contact 714 are connected via the slide contact brush 73 while the first common contact 711 is conductive, and a signal is output from the slide switch SW3.

  At this time, the first dial contact brush 53 and the second dial contact brush 54 also move in the diagonally forward right direction. However, looking at the positional relationship with the lower dial contact pattern 52, the lower contact portion 532 of the first dial contact brush remains in contact with the fifth contact 523 and the eighth contact 522, but below the second dial contact brush. The contact part 542 is detached from the second common contact 521 and contacts the insulating part. For this reason, since the conduction of the second common contact 521 is cut off, the signal of the dial switch SW2 is not output.

  Further, as shown in FIG. 20, when the dial knob 15 is slid in the diagonally rightward direction, for example, the slide contact brush 73 moves diagonally in the diagonally rightward direction, and the contact portion 731 has the first common contact 711 and the first contact. 712 contacts the third contact 714. As a result, the first contact 712 and the third contact 714 are connected via the slide contact brush 73 in a state where the first common contact 711 is conducted, and a signal from the slide switch SW3 is output.

  At this time, the first dial contact brush 53 and the second dial contact brush 54 also move obliquely rearward to the right. However, looking at the positional relationship with the lower dial contact pattern 52, the lower contact portion 541 of the second dial contact brush remains in contact with the second common contact 521, but this time the lower contact portion of the first dial contact brush. 531 comes off from both the eighth contact 522 and the fifth contact 523 and contacts the insulating portion. For this reason, even if the second common contact 521 is conductive, it is not connected to either the eighth contact 522 or the fifth contact 523, so that a signal from the dial switch SW2 is not output.

  As described above, in the composite switch SW of this embodiment, when the dial knob 15 is simultaneously rotated when the slide switch SW3 is operated, the dial switch SW2 does not function electrically, and interference between both switches is prevented. Be safe. Therefore, even when the driver slides the dial knob 15 and scrolls the map displayed on the display, for example, the dial knob 15 is accidentally rotated, the screen is thereby switched. In addition, there is an effect that a malfunction such as a change in sound volume is eliminated and a reliable switch operation is guaranteed.

  In the embodiment described in detail above, the composite switch SW is applied to the operation switch of the car navigation device, but the application of the present invention is not limited to this. Even if this composite switch SW is applied to a switch for operating another device mounted on the vehicle, such as a car audio device or a car air conditioner, the same effect can be obtained.

  Further, the slide switch SW3 is a switch that slides in eight directions diagonally forward, backward, left and right, but the sliding direction is not limited to eight directions, and the number of contacts of the slide contact pattern 71 and the slide contact brush 73 can be changed as appropriate. Any number of slide directions can be set.
