[Best Mode for Carrying Out the Invention]

A switch according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 shows the circuit configuration of an illumination system using the same switch. The switch 1 is connected in series between the load L of the incandescent lamp, the fluorescent lamp or the LED bulb and the AC power source to control the supply of the load L. The switch 1 includes an opening and closing unit 2, a transformer 3, an ON display LED (display light source) 4, a diode 5, a resistor 6, an OFF display LED (display light source) 7, a resistor 8, and a diode 9, and the like. .

The opening and closing unit 2 is connected in series to a circuit including a load L, an AC power source, and a primary coil 3a of the transformer 3. The transformer 3 is excited by the alternating current input to the primary coil 3a when the opening and closing unit 2 is closed, and the alternating current is outputted from the secondary coil 3b. The ON display LED 4 emits light by receiving power from the secondary coil 3b, and the display load L is intended to be in operation. As the LED 4 for ON display, for example, an LED of red or orange is applied. The diode 5 is connected in parallel with the ON display LED 4 in a manner corresponding to the alternating current. The resistor 6 is connected in series between the secondary coil 3b and the ON display LED 4 to limit the current flowing through the ON display LED 4, and adjust the brightness of the ON display LED 4 degree. The OFF display LED 7 is connected in parallel with the opening and closing unit 2, and emits light when the opening and closing unit 2 is open, and the display load L is inoperative. As the LED 7 for OFF display, for example, a green or blue LED is applied. The resistor 8 is connected in series with the OFF display LED 7 to limit the current flowing through the OFF display LED 7. The diode 9 is connected in reverse parallel with the OFF display LED 7 in a manner corresponding to the alternating current. When the opening and closing unit 2 is opened, in order to prevent the load L from malfunctioning (for example, lighting in the case of an illumination device), the resistance of the resistor 8 connected in series with the OFF display LED 7 is increased. Further, since the induced electromotive force is not induced in the secondary coil 3b of the transformer 3, the ON display LED 4 is not lit.

FIG. 2 shows a schematic configuration of the switch 1. The switch 1, called a key switch, is a switch that opens and closes by a key touch operation. The switch 1 is composed of a switch body 10, an operation handle 11, a mounting frame 12, a cosmetic cover 13, and the like. The operation handle 11 is formed of an insulating resin material and is attached to the front surface of the switch body 10 to be operated by a user. The mounting frame 12 is formed, for example, by press working a metal plate, and is mounted on the forming surface 100 (refer to FIG. 3). The switch body 10 is mounted inside the mounting frame 12, and the switch body 10 is supported by the mounting frame 12. 2, the two switch bodies 10 and the operating handle 11 are attached to the mounting frame 12, but the number of the switch body 10 and the operating handle 11 may be one or three or more. The cosmetic cover 13 is formed of a resin material or the like and is attached to the front surface of the mounting frame 12 to decorate the front surface of the switch 1, particularly the periphery of the mounting frame 12.

Figure 3 shows a cross section of the switch 1. The switch body 10 includes the opening and closing unit 2, the transformer 3, the ON display LED 4, the diode 5, the resistor 6, the OFF display LED 7, the resistor 8, and the diode 9 shown in Fig. 1 . In the present embodiment, a bullet-type LED is applied to the ON display LED 4, and a wafer-type LED is applied to the OFF display LED 7. The bullet-type LED used as the LED 4 for ON display can illuminate the light in the direction of the optical axis by the condensing action, even in the case where the illuminating device as the load L is turned on (the state around the switch 1 is bright) The output light can still be visually confirmed simply. On the other hand, the OFF display LED 7 can be used to visually confirm the output light when the lighting fixture as the load L is turned off (the dark state around the switch 1), and therefore a wafer type LED is used.

Further, the switch body 10 further includes terminal plates 14a, 14b, and 14c, a reverse handle 15, a button handle 16, a circuit board 17, a peripheral body 18, a cover 19, and the like. Terminal board 14a, one The end is connected to the electric wire 101 to which the AC power source and the switch 1 are connected, and the other end is connected to the opening and closing unit 2. The front end portion of the electric wire 101 is biased by a spring member (not shown) to maintain the connection state of the electric wire 101 and the terminal plate 14a. The terminal block 14b has one end connected to the primary coil 3a of the connection transformer 3, and the other end connected to the electric wire 102 connecting the switch 1 and the load L. The front end portion of the electric wire 102 is also biased by a spring member (not shown) to maintain the connection state of the electric wire 102 and the terminal block 14b. The terminal plate 14c has one end connected to the primary coil 3a of the transformer 3 and the other end connected to the opening and closing portion 2. The transformer 3 may be provided in the vicinity of the opening and closing portion 2 (between the electric wire 101 and the electric wire 102).

The reverse handle 15 is pivotally supported by the outer peripheral body 18 so that the driving force in the reciprocating direction input from the button handle 16 is converted into the driving force in the rotational direction, and is transmitted to the opening and closing portion 2. The button handle 16 is supported by the cover body 19 in an arbitrarily reciprocating manner, and transmits the driving force input from the operation handle 11 to the reverse handle 15.

The printed circuit board 17 is equipped with an ON display LED 4, a diode 5, a resistor 6, an OFF display LED 7, and a resistor 8. Instead of the printed circuit board 17, a mounting member for inserting a metal plate (lead) to which the above-described respective components are connected may be inserted. In this case, the mounting member is formed in a block shape by an insulating resin material. The ON display LED 4 and the OFF display LED 7 are disposed on the front surface side of the switch 1. The ON display LED 4 and the OFF display LED 7 mounted on the printed circuit board 17 are placed on the surface of the substrate in such a manner that the heights of the bottom surfaces thereof are uniformly matched. The same applies to the use of block-shaped mounting members. The light emitted from the ON display LED 4 and the OFF display LED 7 can be visually confirmed from the outside of the switch 1 by transmitting the first light guide 41, the second light guide 42, the light distribution 43 and the like which will be described later, and the load L is confirmed. action. The ON display LED 4 and the OFF display LED 7 may be attached to a mounting member made of an insulator such as a resin material.

The outer peripheral body 18 is formed of an insulating resin material, and houses the opening and closing unit 2, the transformer 3, the terminal plates 14a, 14b, and 14c, the reverse handle 15, and the circuit board 17, and separates the outer circumference of the switch body 10. The lid body 19 is formed of an insulating resin material and is attached to the opening of the front surface of the outer peripheral body 18.

In Fig. 3, the closed state of the opening and closing portion 2 is indicated by a solid line, and the opening and closing portion 2 is opened with a broken line. Road status. The opening and closing unit 2 is configured by a movable plate 21, a movable contact 22, a fixed contact 23, and the like. The movable plate 21 is rotatably housed in the outer peripheral body 18, and is electrically connected to the terminal plate 14a. The movable contact 22 is formed on the front end side of the movable panel 21. The fixed contact 23 is formed in the terminal block 14c opposite to the movable contact 22. The front end of the reversing handle 15 is engaged with the front end of the movable plate 21, and the movable plate 21 is rotated in conjunction with the rotation of the reversing handle 15, so that the opening and closing portion 2 is opened and closed.

Each time the operation handle 11 is pressed by the user, the driving force is sequentially transmitted to the button handle 16 and the reverse handle 15, and the movable plate 21 is driven to open and close the opening and closing portion 2. Since this series of operations is the same as the switch shown in Patent Document 1 and the like, the description thereof will be omitted.

The switch 1 has a configuration in which the output light of the ON display LED 4 or the OFF display LED 7 is emitted to the outside of the switch 1 , and includes the first light guide 41 , the second light guide 42 , and the light distribution body 43 . When the ON display LED 4 or the OFF display LED 7 emits light, the output light is sequentially transmitted through the second light guide 42 and the first light guide 41, and is emitted from the light distribution body 43.

4 shows the switch body 10 and the operating handle 11 mounted on the front surface of the switch body 10. The casing of the switch body 10 is configured by an outer peripheral body 18, a lid body 19, and the like. As shown in FIG. 3, the outer peripheral body 18 houses the main components constituting the switch 1 such as the opening and closing unit 2, the transformer 3, the terminal plates 14a, 14b, and 14c, the reverse handle 15, the circuit board 17, and the second light guide 42. The second light guide body 42 is formed of a resin material having a porous property, and guides the output light of the ON display LED 4 and the OFF display LED 7 to the first light guide 41 . The second light guide body 42 is fitted to the 19b formed in the front surface through hole of the lid body 19. In the cover 19, the button handle 16 is assembled. The button handle 16 is disposed on the side of the operation portion 11c of the operation handle 11, that is, on the side away from the bearing portion 11b. Therefore, the stroke of the operating handle 11 can be set to an appropriate value to obtain good operability.

The lid body 19 has a support shaft 19a and a through hole 19b. The support shaft 19a forms an end edge of the lid body 19 in the vicinity of the second light guide body 42, and is fitted to the bearing portion 11b of the operation handle 11, and the operation handle 11 is rotatably supported. The through hole 19b penetrates the front wall surface of the lid body 19 in the vicinity of the support shaft 19a. The second light guide 42 is fitted into the through hole 19b, and the ON display LED 4 and the OFF display are displayed. The output light of the display LED 7 is emitted.

The operation handle 11 has a display portion 11a, a bearing portion 11b, an operation portion 11c, a first light guide 41, and a light distribution body 43. The display portion 11a is formed on the side of the operation portion 11c that is away from the bearing portion 11b. Here, the side away from the bearing portion 11b is such that when the bearing portion 11b is the base end of the operation handle 11, the side closer to the front end than the center portion of the operation handle 11 does not have to be the end edge portion of the operation handle 11. The light distribution body 43 is fitted into the through hole formed in the display portion 11a, and the output light of the ON display LED 4 and the OFF display LED 7 is emitted from the light distribution body 43. The bearing portion 11b is formed in a pair with the first light guide 41 in the vicinity of the end edge of the back surface of the operation handle 11 corresponding to the support shaft 19a. By fitting the bearing portion 11b to the support shaft 19a, the operation handle 11 can be supported by the switch body 10 in an arbitrary rotation manner. The operation portion 11c is provided on a side away from the bearing portion 11b so as to be a portion that is pressed by the user. In other words, the light distribution member 43 is fitted into the through hole formed in the display portion 11a of a portion constituting the operation portion 11c. The first light guide 41 is joined to the operation handle 11 by, for example, thermal fusion welding such as ultrasonic welding. Thereby, the fixing member for joining the two is not required, and the configuration of the switch 1 can be simplified. Since the first light guide 41 and the light distribution body 43 are provided on the operation handle 11, they are integrally rotated in accordance with the rotation of the operation handle 11.

The first light guide 41 is formed of a resin material or the like having a porous property, and is assembled to the back surface of the operation handle 11. The first light guide 41 guides the output light of the ON display LED 4 and the OFF display LED 7 emitted from the second light guide 42 to the light guide, and is disposed on the side away from the bearing portion 11b, that is, in the operation portion 11c. The light distribution body 43 on the side.

The light distribution body 43 distributes the output light of the ON display LED 4 and the OFF display LED 7 guided by the first light guide 41 to a desired range and emits the light. Since the light distribution body 43 is provided in the region constituting the operation portion 11c, the user can operate the operation portion 11c by the output light of the ON display LED 4 and the OFF display LED 7 emitted from the light distribution body 43. For example, the operation portion 11c can be easily operated by relying on the output light of the OFF display LED 7 in the dark.

FIG. 5 shows the first light guide 41. The first light guide 41 has a first incident portion 41a, a first reflecting portion 41b, a first light guiding portion 41c, a second reflecting portion 41d, and a first emitting portion 41e. 1st The incident portion 41a is provided at one end of the first light guide 41, and the output light of the ON display LED 4 and the OFF display LED 7 emitted from the second light guide 42 is incident. The first reflecting portion 41b is provided between the first incident portion 41a and the first light guiding portion 41c, and reflects the output light incident from the first incident portion 41a, and directs the light toward the first light guiding portion 41c. The direction of 11c changes. The first light guiding portion 41c is provided between the first reflecting portion 41b and the second reflecting portion 41d, and guides the output light reflected by the first reflecting portion 41b to the second reflecting portion 41d disposed on the side of the operation portion 11c. The second reflecting portion 41d is disposed between the first light guiding portion 41c and the first emitting portion 41e, and reflects the output light guided from the first light guiding portion 41c to change the direction of the light toward the first emitting portion 41e. . The first emitting portion 41e is provided at the other end of the first light guiding body 41, and emits the output light reflected by the second reflecting portion 41d.

When the operation handle 11 is attached to the switch main body 10, the first light guide 41 is assembled to the operation handle 11 so that the first incident portion 41a and the second emission portion 42c of the second light guide 42 face each other. . The thickness dimension T1 of the first light guiding portion 41c in the depth direction of the switch 1 is set to be smaller than the thickness dimension T2 in the depth direction of the switch 1 from the first incident portion 41a to the first reflecting portion 41b. Thereby, the first light guiding portion 41c can be disposed in the gap between the operation handle 11 and the button handle 16, and when the operation handle 11 is operated, the first light guiding portion 41c interferes with the lid body 19 and the like, thereby hindering the rotation of the operation handle 11. . Further, the driving force applied to the operation portion 11c of the operation handle 11 via the first light guiding portion 41c may be transmitted to the button handle 16. In addition, when the first incident portion 41a of the first light guide 41 is brought close to the second emitting portion 42c of the second light guide 42, the light emitted from the second emitting portion 42c can be efficiently incident on the first light. The incident portion 41a. Further, it is possible to suppress leakage of light emitted from the second emitting portion 42c from the periphery of the operation handle 11.

FIG. 6 shows the second light guide 42. The second light guide 42 has a second incident portion 42a, a second light guiding portion 42b, and a second emitting portion 42c. The second incident portion 42a is formed in a hierarchical shape (stepped shape) in accordance with the ON display LED 4 (bullet type LED) and the OFF display LED 7 (wafer type LED) which are different in height from the tip end portion. By this, the second incident portion 42a of the second light guide 42 is brought close to the emission portion of the ON display LED 4 and the OFF display LED 7, so that the light emitted from the light source can be efficiently incident on the second incident portion 42a.

Further, the first reflection portion 41b of the first light guide 41 is disposed on the optical axis of any one of the plurality of display light sources (for example, the ON display LED 4). On the other hand, the first reflection portion 41b is not disposed on the optical axis of the OFF display LED 7. Thereby, the output light of the ON display LED 4 can be made bright, and the output light of the OFF display LED 7 can be displayed softly and weakly. By disposing the first reflecting portion 41b on the optical axis of the OFF display LED 7, the OFF display LED 7 can also be displayed brightly.

The first incident portion 41a and the second incident portion 42c are separated from each other so that the first incident portion 41a of the first light guide 41 does not interfere with the second emitting portion 42c of the second light guide 42 and interferes with the rotation of the operation handle 11. The scheduled interval configuration. In the present embodiment, since the first incident portion 41a is located in the vicinity of the support shaft 19a which is the center of rotation of the operation handle 11, the movement of the first incident portion 41a accompanying the rotation of the operation handle 11 is suppressed. Therefore, interference between the first incident portion 41a and the second emitting portion 42c is less likely to occur, and the interval between the first incident portion 41a and the second emitting portion 42c is set to a small interval, and the second emitting portion 42c can be emitted. The light is efficiently incident on the first incident portion 41a.

FIG. 7 shows that the output light of the ON display LED 4 is guided by the second light guide 42 and the first light guide 41 to be emitted from the light distribution body 43. In addition, FIG. 8 shows that the output light of the OFF display LED 7 is guided by the second light guide 42 and the first light guide 41 to be emitted from the light distribution body 43. The output light of the ON display LED 4 and the OFF display LED 7 is appropriately reflected by the end surface of the second light guide 42 and is incident on the first light guide 41. The output light incident on the first light guide 41 is appropriately reflected by the end faces of the first light guides 41c in addition to the first reflection portions 41b and the second reflection portions 41d, and is incident on the light distribution body 43.

The first reflection portion 41b of the first light guide 41 is formed of a paraboloid or an elliptical surface. According to the configuration in which the first reflecting portion 41b is formed of a paraboloid, the output light emitted from the plurality of light sources can be efficiently reflected and guided to the first light guiding portion 41c. Further, in a configuration in which the first reflecting portion 41b is formed in an elliptical surface, the output light emitted from one of the plurality of light sources can be particularly efficiently reflected and guided to the first light guiding portion 41c.

Further, on the surface of the light distribution body 43, tantalum is formed. Thereby, the transmission light distribution body 43 is not made When the amount of light is lowered, it is difficult to observe the internal structure of the switch 1 from the outside of the light distribution body 43. Further, the light distribution body 43 is made of, for example, a light-transmitting material containing a light-diffusing material. Thereby, it becomes difficult to observe the internal structure of the switch 1 from the outer side of the light distribution body 43. Further, when the output light of the ON display LED 4 and the OFF display LED 7 is transmitted through the light distribution body 43, the light diffusing material is diffused, and uniform and weak soft light can be emitted.

According to the switch 1 of the present embodiment having the above configuration, the output light of the ON display LED 4 and the OFF display LED 7 is emitted from the operation portion 11c side of the operation handle 11 away from the light source. Thereby, it is possible to maintain good operability, and it is possible to perform an intuitive operation to improve usability. In addition, since the ON display LED 4 and the OFF display LED 7 are disposed at positions away from the operation portion 11c having a large movement amount, it is possible to prevent the output light of the ON display LED 4 and the OFF display LED 7 from leaking from the periphery of the operation handle 11. .

Further, since the operation handle 11 has the first light guide 41 that guides the output light of the ON display LED 4 and the OFF display LED 7 to the operation portion 11c side, the operation handle 11 has a simple configuration and can move the load L away from the operation state. The light source is displayed on the side of the operation portion 11c.

Since the second light guide 42 is provided between the rotating first light guide 41 and the ON display LED 4 and the OFF display LED 7 of the light source, the output light of the light source can be efficiently guided to the first light guide. 41.

Since the first light guide 41 has the first incident portion 41a, the first reflecting portion 41b, the first light guiding portion 41c, and the first emitting portion 41e, the first light guiding body 41 has a simple configuration and can change the direction of the output light of the light source. The first emitting unit 41e is guided. In addition, since the thickness T1 of the first light guiding portion 41c is smaller than the thickness T2 of the portion from the first incident portion 41a to the first reflecting portion 41b, the first light guiding portion 41c is prevented from interfering with the switch body 10 and the like. The situation in which the rotation of the operating handle 11 is hindered.

Since a plurality of types of LEDs 4 and 7 are provided as the light source for display, the display of the display unit can be switched in accordance with the operation state of the load L, and the usability of the switch 1 can be improved.

Further, since the plurality of types of LEDs 4 and 7 are attached to the circuit board 17, the LEDs 4 and 7 can be easily mounted for a simple configuration, and the cost of the switch 1 can be reduced. Further, since the second incident portion 42a of the second light guide 42 is formed in a hierarchical shape corresponding to the front ends of the LEDs 4 and 7, the second incident portion 42a can be brought close to the emitting portions of the LEDs 4 and 7, and the self-light source can be obtained. The emitted light is efficiently incident on the second incident portion 42a.

Further, since the first reflecting portion 41b of the first light guiding body 41 is formed of a paraboloid or an elliptical surface, the output light emitted from the plurality of light sources or the output light emitted from the one light source can be efficiently reflected and guided to the first 1 light guiding portion 41c.

Further, since the first reflection portion 41b of the first light guide 41 is disposed on the optical axis of the ON display LED 4, the output light of the ON display LED 4 can be brightly displayed. On the other hand, since the first reflection portion 41b is not disposed on the optical axis of the OFF display LED 7, the output light of the OFF display LED 7 can be displayed weakly and softly. In this manner, by arranging the first reflecting portion 41b on the optical axis of any of the light sources, the output light of the light source can be displayed brightly. Further, by disposing the first reflection portion 41b on the optical axis of the OFF display LED 7, the OFF display LED 7 can also be displayed brightly.

Further, since the operation handle 11 has the light distribution body 43, the output light of the LEDs 4 and 7 can be distributed in a desired range and emitted, thereby improving the ease of use of the switch 1. Further, since 稜鏡 is formed on the surface of the light distribution body 43, it is difficult to observe the internal structure of the switch 1 from the outside of the light distribution body 43 without reducing the amount of light transmitted through the light distribution body 43, and the commercial value of the switch 1 is improved. . Further, since the light distribution body 43 is made of a light-transmitting material containing a light-diffusing material, it is difficult to observe the internal structure of the switch 1 from the outside of the light-receiving body 43. Further, when the output light of the LEDs 4 and 7 is transmitted through the light distribution body 43, the light diffusing material is diffused to emit a uniform and weak soft light, and the commercial value of the switch 1 is improved.

Further, the present invention is not limited to the configuration of the above embodiment. At least the operation handle 11 is supported on the LEDs 4 and 7 side by the arbitrarily rotating of the switch body 10, and the output light of the LEDs 4 and 7 is emitted from the side of the operation portion 11c of the operation handle 11 away from the LEDs 4 and 7. Just fine.

Further, the invention can be variously modified. For example, the ON display LED 4 and the OFF display LED 7 used as the display light source are not limited to a bullet-type or wafer-type LED, and may be other types of LEDs. Further, the light source for display is not limited to an LED, and may be a light source such as a xenon lamp or an organic EL (Electro-Luminescence).

In addition, the display light source can be arranged close to the first incident portion 41a of the first light guide 41, and the second light guide 42 is not used. Further, the first light guide 41 and the light distribution body 43 may be integrally formed.

In addition, the load L is not limited to lighting fixtures such as incandescent lamps, fluorescent lamps or LED bulbs, and may be other electrical appliances. Further, the switch body 10 is not limited to the configuration of the outer peripheral body 18 or the lid body 19, and may be in the form of replacement with other components or addition of other components.
