Next, the internal structure of the switch 2 will be explained. Fig. 3 is a schematic exploded perspective view showing an example of the switch 2 described in the present application. FIG. 4 is a schematic cross-sectional view showing an example of a cross-section of the switch 2 described in the present application. Fig. 4 is a cross-section showing the following from a front view, and the cross-section is a cross section cut by a vertical plane including the line segment A-B shown in Fig. 2.

In the housing 20 of the switch 2, an area as the storage chamber 202 that houses an opening and closing mechanism for opening and closing an electric circuit is secured. The upper surface of the storage chamber 202 is provided with an insertion hole 200 and an adjustment hole 201 penetrating from above the housing 20. In the insertion hole 200, the pressing member 21 is inserted, and in the adjustment hole 201, the engagement screw 220 of the movable magnet 22 is engaged.

The opening and closing mechanism housed in the storage room 202 will be described. In the storage chamber 202, as an opening and closing mechanism, in addition to the pressing member 21, the movable magnet 22, and the magnetic field detector 24, various members such as a movable member 25 and a connecting member 26 are arranged. The magnetic field detection unit 24 is arranged on the lower left side of the storage chamber 202. The movable member 25 fixes the first end side so as to be magnetically connected to the magnetic field detector 24, and is arranged from the first end side to the second end side, which is the opposite free end, to extend left and right in the storage chamber 202. The pressing member 21 and the movable magnet 22 are arranged on the upper right side of the storage chamber 202. The pressing member 21 and the movable magnet 22 abut against the movable member 25 at the lower end. The connecting member 26 is arranged from the top surface in the storage chamber 202 to the inner side surface on the left side, and magnetically connects the movable magnet 22 and the magnetic field detection unit 24.

The pressing member 21 has a substantially rectangular parallelepiped shape, and the upper surface and the lower surface are formed into curved surfaces. The pressing member 21 abuts against the movable member 25 at the lower end, and when it is pressed from the outside and moves from the top dead center to the bottom dead center, the movable member 25 is pressed downward. In addition, when the pressing member 21 is released from the outside, the magnetic force of the movable magnet 22 that attracts the movable member 25 and the force applied by the movable member 25 formed in the shape of a leaf spring move from the bottom dead center to the top dead center. mobile.

The movable magnet 22 is formed using a permanent magnet, and has a substantially rectangular parallelepiped shape that is long back and forth. In the upper part of the movable magnet 22, an engagement screw 220 that is engaged with the connecting member 26 is inserted. The engaging screw 220 of the movable magnet 22 can be slidably engaged with the engaging receiving portion 260 formed as a notch extending from the right end side of the connecting member 26 along the adjusting hole 201. By loosening the engaging screw 220 of the movable magnet 22, the movable magnet 22 can move left and right along the adjustment hole 201, and by tightening the engaging screw 220, the arrangement position of the movable magnet 22 can be fixed. As described above, the movable magnet 22 is configured to be movable in the left-right direction.

When the pressing member 21 is at the top dead center and the movable member 25 is not pressed, the movable member 25 flexes the free end side upward by the restoring force as a leaf spring, and contacts the lower end of the pressing member 21. Furthermore, the movable member 25 near the movable magnet 22 is also attracted by the magnetic force of the movable magnet 22. When the pressing member 21 is pressed down to the bottom dead center, the pressing member 21 presses between the fixed end that becomes the left end side of the movable member 25 and the contact portion with the movable magnet 22 and the movable member 25. As the movable member 25 is bent downward due to the pressing of the pressing member 21, the movable member 25 is separated from the movable magnet 22. The contact position of the movable magnet 22 and the movable member 25 can be changed by adjusting the arrangement position of the movable magnet 22. In addition, in the movable magnet 22, the upper magnetic pole in contact with the connecting member 26 and the lower magnetic pole in contact with the movable member 25 have different polarities.

The magnetic field detection unit 24 includes a Hall element 240 that uses the Hall effect to detect a magnetic field, and is configured using a Hall integrated circuit (IC). The Hall IC is detected from the output terminal 24a based on the Hall element 240. The magnetic field changes to output the on signal. The Hall element 240 is molded as a substantially rectangular parallelepiped chip, which is arranged at the lower left of the housing chamber 202 of the housing 20. Three output terminals 24a connected to the molded Hall element 240 are from the bottom of the housing 20. The surface is prominent. There are various types of Hall elements such as single-sided detection that detects the approach of magnetic flux from one pole, double-sided detection that detects the approach of magnetic flux from two poles, and alternate detection that detects changes in magnetic flux. However, in the above-mentioned embodiment, it is preferably a Hall element with single-side detection or double-side detection.

In the housing 20, a connecting member 26 is arranged on the left side of the Hall element 240, and on the right side of the Hall element 240, the left end side serving as the fixed end of the movable member 25 is fixed. The movable member 25 and the connecting member 26 located on the left and right of the Hall element 240 are magnetically connected to the Hall element 240 of the magnetic field detection unit 24. The so-called magnetic connection here refers to contact or proximity to the extent that the magnetic field caused by the magnetic flux of the movable member 25 and the connecting member 26 will affect the detection and output of the Hall element 240.

The movable member 25 is a member formed by bending a long thin sheet formed using a paramagnetic material such as iron and steel into a leaf spring shape. The left end (first end) side of the movable member 25 is fixed to the left side of the magnetic field detection unit 24 as a fixed end. The movable member 25 extends upward from the fixed end side and flexes to extend to the right side, and the right end (second end) side becomes a free end. The movable member 25 has flexibility, the free end is swingable, and also functions as a leaf spring that urges upward.

When the movable member 25 is located at the upper end of the swing range, the movable magnet 22 is in contact with the right end side, which is a free end, with respect to the portion of the movable member 25 extending in the left-right direction. The pressing member 21 presses between the contact portion of the movable magnet 22 and the left end side serving as the fixed end. The contact location of the movable magnet 22 with the movable member 25 can be changed as described above. In addition, the movable member 25 is pressed by the pressing member 21 to bend downward, and when the self-pressing is released, the magnetic force from the movable magnet 22 and the function as a leaf spring urge the movable member 25 upward.

The connecting member 26 is a member formed by bending and molding an elongated plate-shaped body formed of a paramagnetic material such as iron or steel, and is arranged from the top surface of the housing chamber 202 in the frame 20 along the inner side surface on the left side. In the connecting member 26, on the right end side of the portion arranged on the top surface, an engagement receiving portion 260 for guiding the movement of the movable magnet 22 is formed as a cutout. The engagement receiving portion 260 is shaped into a wave shape to assist the positioning of the movable magnet 22. On the left side of the engagement receiving portion 260, an insertion opening 261 through which the pressing member 21 is inserted is opened. The connecting member 26 is physically connected to the movable magnet 22 via the engagement receiving portion 260 and is magnetically connected to the movable magnet 22. As described above, the connecting member 26 is magnetically connected to the Hall element 240 of the magnetic field detection unit 24 by the part arranged along the inner side surface of the left side in the storage chamber 202. Furthermore, the insertion opening 261 of the connecting member 26 is opened with a sufficient size with respect to the pressing member 21 and therefore does not contact the pressing member 21.

Next, the operation of the switch 2 described in the present application will be described. 5A and 5B are schematic cross-sectional views showing an example of the switch 2 described in the present application. FIG. 5A shows a state where the pressing member 21 is not pressed from the outside, and FIG. 5B shows a state where the pressing member 21 is pressed from the outside and moves downward.

As shown in FIG. 5A, when the pressing member 21 is not pressed from the outside, the pressing member 21 is located at the top dead center, and the free end side of the movable member 25 is in contact with the movable magnet 22. Under the conditions described above, the movable magnet 22 formed using a permanent magnet is magnetically connected to the left side of the Hall element 240 via the connecting member 26, and is also magnetically connected to the right side of the Hall element 240 via the movable member 25. The movable member 25 and the connecting member 26 are formed using paramagnetic materials, and therefore function as a yoke, allowing the magnetic flux from the movable magnet 22 to pass through. In the movable magnet 22, the upper magnetic pole in contact with the connecting member 26 and the lower magnetic pole in contact with the movable member 25 have different polarities. Therefore, the movable magnet 22, the movable member 25, and the connecting member 26 have different polarities. The magnetic flux flowing in the direction indicated by the hollow arrow in 5A passes through. The movable member 25 and the connecting member 26 are arranged on the left and right sides relative to the Hall element 240, so the magnetic flux passing through the Hall element 240 forms a magnetic field detectable by the Hall element 240.

As shown in FIG. 5B, when the pressing member 21 is pressed from the outside, the pressing member 21 is located at the bottom dead center, and the movable member 25 is pressed downward and is separated from the movable magnet 22. In the above-mentioned situation, the magnetic flux that exits from the movable magnet 22 and passes through the Hall element 240 is not formed. Therefore, the magnetic field detectable by the Hall element 240 is changed by the pressing of the pressing member 21. The change in the magnetic field detected by the Hall element 240 is output from the output terminal 24a as a signal indicating the change in current, and is output from the switch 2 to the operating device 1 as a conductive signal.

When the user presses down the operating portion 10 of the operating device 1 from the state shown in FIG. 5A, the pressing member 21 of the switch 2 is pressed to move to the bottom dead center, and transition to FIG. 5B In the state shown, the switch 2 outputs the pilot signal to the operating device 1. The pressing operation requires the force of separating the movable member 25 in contact with the movable magnet 22 against the magnetic force, so the user feels an enhanced click feeling.

Next, the position adjustment of the movable magnet 22 of the switch 2 described in this application will be explained. 6A and 6B are schematic diagrams showing an example of a dynamic model of the movable magnet 22 and the movable member 25 included in the switch 2 described in the present application. 6A shows a state where the movable magnet 22 is moved to a position close to the left side of the fixed end, and FIG. 6B shows a state where the movable magnet 22 is moved to a position close to the right side of the free end. In FIGS. 6A and 6B, the arrows indicate the pressing position and direction of the pressing member 21. As shown in FIGS. 6A and 6B, the movable member 25 uses the fixed end indicated by a white circle as a fulcrum, and is pressed to the pressing position and direction indicated by the arrow to swing. As shown in FIG. 6A, by bringing the movable magnet 22 close to the fixed end side that becomes the fulcrum, the operation load (hereinafter referred to as the operating force (Operation Force, OF)) during pressing is reduced, and the The length of the pressing distance of the pressing member 21 (hereinafter referred to as a pre-travel (Pre Travel, PT)) until the movable member 25 swings to output a signal is shortened. In addition, as shown in FIG. 6B, by bringing the movable magnet 22 closer to the free end side serving as the point of action, the OF at the time of pressing increases and the PT becomes longer. Especially when the distance between the pressing position and the movable magnet 22 becomes longer and the OF during pressing increases, the degree of deflection of the movable member 25 increases, so the PT is extended to the distance between the pressing position and the movable magnet 22 More than the degree of change. Conversely, the closer the movable magnet 22 is to the fixed end side, the smaller the degree of deflection and the smaller the influence of deflection on the PT. As described above, by moving the movable magnet 22, the OF and PT can be adjusted, so that the operating feeling can be adapted to the user's preference.

<The second embodiment> The second embodiment is a form in which the permanent magnet is fixed in the first embodiment. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and the first embodiment is referred to, and detailed descriptions are omitted.

FIG. 7 is a schematic perspective view showing an example of the appearance of the switch 2 described in the present application. The switch 2 includes a frame 20 having a substantially rectangular parallelepiped shape. The upper surface of the housing 20 is provided with a rectangular insertion hole 200 through which the pressing member 21 is inserted. Furthermore, in the second embodiment, the movable magnet 22 is not used, so the adjustment hole 201 shown in the first embodiment is not opened.

The mounting legs 23, the three output terminals 24a, and the two fixing legs 26a for fixing the switch 2 to an external member such as a substrate protrude from the lower surface of the housing 20.

In addition, when the pressing member 21 is released from the outside, it moves from the bottom dead center to the top dead center by the force applied by the movable member 25 formed in the shape of a leaf spring.

The fixed magnet 27 is formed using a permanent magnet and has a substantially rectangular parallelepiped shape. At the lower end of the fixed magnet 27, the connecting member 26 is magnetically connected. Above the fixed magnet 27, a movable member 25 is arranged.

FIG. 17 is a schematic cross-sectional view showing an example of a cross-section of the switch 2 described in the present application. FIG. 18 is a schematic perspective view showing an example of a part of the internal structure of the switch 2 according to the present application. FIG. 16 shows in the form of a schematic perspective view the internal components of the housing 20 from which the switch 2 has been removed. FIG. 18 shows in a perspective view a part of the internal components of the housing 20 detached from the switch 2 and schematically shows the direction of the magnetic flux and the magnetic poles superimposed. In the storage chamber 202, members such as a pressing member 21, a magnetic field detecting portion 24, a movable member 25, and a fixed magnet 27 are arranged as an opening and closing mechanism, and a fixed member 28 supporting the movable member 25 is also arranged.

The fixing member 28 is a member formed by molding a metal plate, and is fixed in the storage chamber 202. The fixing member 28 is formed with a standing leg portion 280, a first support portion 281, a second support portion 282, a first contact portion 283, and a second contact portion 284. The standing leg 280 is inserted into the position of the base 20a of the frame 20, and by inserting the erect leg 280 into the base 20a of the frame 20, the fixing member 28 is erected in the receiving chamber of the frame 20 202 within. The first support portion 281 is a portion protruding upward on the left end side in the storage chamber 202 and supports the movable member 25 in a swingable manner. The second support portion 282 is a portion protruding upward in the vicinity of the center in the storage chamber 202 and supports the movable member 25 in a swingable manner. The first abutting portion 283 abuts on the part of the swinging movable member 25 from the lower right side, and restricts the swing range of the movable member 25 from below. The second abutting portion 284 abuts on the part of the swinging movable member 25 from the upper right side, and restricts the swing range of the movable member 25 from above.

The movable member 25 is a flexible member formed of a thin metal plate using a paramagnetic material such as iron or steel, and is arranged in the storage chamber 202 to extend in the left-right direction. The left end of the movable member 25 becomes a fixed end (first end) that is locked to the first support portion 281 of the fixed member 28 and functions as a swing fulcrum. The right end of the movable member 25 is a free end (second end) that moves between the first abutment portion 283 and the second abutment portion 284, and the swing range of the free end is determined by the first abutment portion 283 and the second abutment portion 284. 284 restrictions. In the movable member 25, an urging part 250 is formed, and the urging part 250 functions as a return spring that is penetrated near the center and bent in an arc shape. The urging part 250 has a substantially rectangular shape in a plan view, the short side on the right side is connected to the outer frame of the movable member 25, and the short side and the two long sides on the left side are divided into tongue-like pieces. The urging part 250 is formed in a shape that is bent into a convex arc shape in the downward direction so that the punched tongue piece part functions as a return spring. The left end of the pierced force applying portion 250 is supported by the second supporting portion 282 located near the center in the containing chamber 202. The urging part 250 generates a reaction force against the pressing of the pressing member 21. The free end side of the movable member 25 becomes a flexion piece 251 whose tip part is bent at a substantially right angle downward.

In the opening and closing mechanism configured as described above, the pressing member 21 is pressed from the outside and moves downward to press the movable member 25. By pressing the movable member 25, the free end of the movable member 25, that is, the right end side, descends until it abuts the first abutting portion 283, and the flexure piece 251 at the front end also moves downward.

When the pressing of the pressing member 21 is released, the reaction force of the urging part 250 urges the movable member 25 toward the upper side. By urging the movable member 25 toward the upper side, the pressing member 21 is moved upward. In addition, by urging the movable member 25 toward the upper side by the urging portion 250, the right end side of the movable member 25 rises and abuts against the second abutting portion 284.

At the fixed end of the movable member 25, a fixed magnet 27 is installed. On the lower right side in the frame 20, below the flexure piece 251 of the movable member 25, the surface of the substrate 3 is packaged with a magnetic field detector 24.

As shown by the hollow arrow in FIG. 18, the magnetic flux from the fixed magnet 27 attached to the fixed end of the movable member 25 flows in the movable member 25 from the fixed end and reaches the flexion piece 251 on the free end side. Near the front end of the, a magnetic field is formed to an extent detectable by the magnetic field detector 24. In FIG. 18, there is shown an example in which the N pole of the fixed magnet 27 is mounted in contact with the fixed end of the movable member 25, and the buckling of the movable member 25 is formed by the magnetic flux flowing in the movable member 25 The tip of the piece 251 is an N pole magnetic field.

Next, the operation of the switch 2 described in this application will be explained. 19A and 19B are schematic cross-sectional views showing an example of the switch 2 described in the present application. FIG. 19A shows a state where the pressing member 21 is not pressed from the outside, and FIG. 19B shows a state where the pressing member 21 is pressed from the outside and moved downward.

As illustrated in FIG. 19A, when the pressing member 21 is not pressed from the outside, the pressing member 21 is located at the top dead center. In the state illustrated in FIG. 19A, the movable member 25 is pushed upward by the urging portion 250 by resisting the reaction force of the pressing of the pressing member 21, so the free end side and the upper right side arranged in the storage chamber 202 The second abutting portion 284 contacts.

As the pressing member 21 moves downward, the pressing member 21 presses the movable member 25 downward. The entire movable member 25 is pressed by the pressing member 21, and is about to move downward with the part locked to the first support portion 281 as the swing axis. However, the movable member 25 is pushed upward by the urging portion 250 by resisting the reaction force of the pressing of the pressing member 21, so the movable member 25 maintains the second contact with the upper right side disposed in the storage chamber 202 The state of 284 contact. Therefore, the movable member 25 receives the pressing force from the pressing member 21 and is in a state of being bent and bent downward.

As the pressing member 21 further moves downward, the entire movable member 25 is pressed by the pressing member 21 and will move downward with the part locked to the first support portion 281 as the swing axis. Then, the urging portion 250 of the movable member 25 swings downward with the position locked to the second support portion 282 as the swing axis, so the entire movable member 25 swings with the first support portion 281 as the swing axis to reverse. The free end side of the movable member 25 abuts against the first abutting portion 283 by the swing using the first support portion 281 as the swing axis. That is, it becomes the state illustrated in FIG. 19B. The movable member 25 collides with the first abutting portion 283 due to the reversal momentum, and therefore is accompanied by an impact. The user recognizes the sound generated by the impact caused by the reversal and the collision and the change in the pressing load as a click sound and a click feeling.

When the pressing of the pressing member 21 is released, the reaction force of the urging part 250 urges the movable member 25 upward. By urging the movable member 25 toward the upper side, the pressing member 21 is moved upward. In addition, by using the urging portion 250 to urge the movable member 25 toward the upper side, the free end side of the movable member 25 rises and abuts against the second abutting portion 284. That is, it becomes the state illustrated in FIG. 19A.

As illustrated in FIG. 19A, when the pressing member 21 is not pressed from the outside, the right end of the movable member 25 is located above, so the lower end of the flexion piece 251 of the movable member 25 is sufficiently isolated from the magnetic field detecting portion 24 toward the upper side.

As illustrated in FIG. 19B, when the pressing member 21 is pressed from the outside, the right end of the movable member 25 is located below, and therefore the lower end of the flexion piece 251 of the movable member 25 is in contact with or close to the magnetic field detecting portion 24. When the front end of the flexure piece 251 is in contact with or close to the magnetic field detecting unit 24, the magnetic field detectable by the Hall element 240 of the magnetic field detecting unit 24 changes. The change in the magnetic field detected by the Hall element 240 is output as a signal indicating the change in current, and is output from the switch 2 to the operating device 1 as a conductive signal.

As described above, the switch 2 described in the present application includes permanent magnets such as the movable magnet 22 and the fixed magnet 27, and the magnetic field detection unit 24 using the Hall element 240. Since the magnetic field detector 24 is used to open and close the circuit, no mechanical contacts are required, and the application range of switches using magnets can be expanded. Especially when a member formed of a paramagnetic material is used, the detection characteristics of the magnetic field can be improved. Specifically, by forming the movable member 25 and the connecting member 26 with paramagnetic material, the paramagnetic material functions as a yoke to increase the magnetic field. Therefore, it is expected that the Hall sensor included in the magnetic field detector 24 The detection characteristics of the element 240 are improved, such as improved detection accuracy and improved noise resistance.

In addition, the switch 2 described in the present application may be configured such that, for example, the contact point of the magnetic field detection unit 24 has two functions of opening and closing of the circuit and a click feeling. For example, when compared with a type of switch that uses an optical element and generates a click sensation by a magnet, the switch 2 described in the present application having two functions has a simple structure and can reduce the cost of the element. It is expected to suppress the increase in manufacturing costs. In addition, the switch 2 described in the present application can adjust the click feeling by the magnetic force of the permanent magnet. In addition, the switch 2 described in the present application can adjust the arrangement position of the movable magnet 22, so that the OF and PT can be adjusted, so that the operating feeling can be matched to the user's preferences, etc., and excellent effects can be obtained.
