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 shows a cross section taken along a vertical plane including the line segment AB shown in FIG. 2 from a front view.

In the housing 20 of the switch 2, an area is secured as a housing chamber 202 for housing an opening/closing mechanism that opens/closes an electric circuit. An insertion hole 200 and an adjustment hole 201 penetrating from above the housing 20 are formed on the upper surface of the accommodation chamber 202. The pressing member 21 is inserted into the insertion hole 200, and the engagement screw 220 of the movable magnet 22 is engaged with the adjustment hole 201.

The opening/closing mechanism housed in the housing room 202 will be described.

The connection member 26 is disposed from the top surface in the accommodation chamber 202 to the inner 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 curved. The pressing member 21 is in contact with the movable member 25 at its lower end, and presses the movable member 25 downward when it receives a pressure from the outside and moves from top dead center to bottom dead center. Further, when the pressing member 21 is released from the external pressure, the magnetic force of the movable magnet 22 attracting the movable member 25 and the urging force from the movable member 25 formed in a leaf spring shape cause the top dead center from the bottom dead center. Move to a point.

The movable magnet 22 is formed by using a permanent magnet, and has a substantially rectangular parallelepiped shape that is long in the front-rear direction. An engaging screw 220 that engages with the connecting member 26 is inserted in the upper portion of the movable magnet 22. The engagement screw 220 of the movable magnet 22 is slidably engaged with an engagement receiving portion 260 formed as a cutout extending from the right end side of the connection member 26 along the adjustment hole 201.

In this way, the movable magnet 22 is arranged so as to be movable in the left-right direction.

When the pressing member 21 is located at the top dead center and the movable member 25 is not pressed, the free end side of the movable member 25 bends upward due to the restoring force as a leaf spring and comes into contact with the lower end of the pressing member 21. In the vicinity of the movable magnet 22, the movable member 25 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 on the left end side of the movable member 25 and the contact portion where the movable magnet 22 contacts the movable member 25. .. The movable member 25 is separated from the movable magnet 22 by bending the movable member 25 downward by the pressing of the pressing member 21. The contact portion where the movable magnet 22 contacts the movable member 25 is changed by adjusting the arrangement position of the movable magnet 22. The upper magnetic pole of the movable magnet 22 that contacts the connecting member 26 and the lower magnetic pole that contacts the movable member 25 have different polarities.

The magnetic field detection unit 24 includes a Hall element 240 that detects a magnetic field using the Hall effect, and is configured using a Hall IC that outputs an ON signal based on a change in the magnetic field detected by the Hall element 240 from an output terminal 24a. It The Hall element 240 is molded as a substantially rectangular parallelepiped chip and is arranged in the lower left part of the housing chamber 202 of the housing 20. The three output terminals 24a connected to the molded Hall element 240 are It projects from the lower surface of the housing 20. Hall elements have various specifications such as one-sided detection that detects the approach of the magnetic flux from one pole, two-sided detection that detects the approach of the magnetic flux from both poles, and alternating detection that detects the change of the poles related to the magnetic flux. However, in this embodiment, a Hall element for one-sided detection or both-sided detection is preferable.

In the housing 20, the connection member 26 is arranged on the left side of the hall element 240, and the left end side, which is the fixed end of the movable member 25, is fixed on the right side of the hall element 240. 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 term “magnetically connected” as used herein means that the magnetic field caused by the magnetic flux of the movable member 25 and the connecting member 26 is in contact with or close to the extent that the detection and output by the Hall element 240 are affected.

The movable member 25 is a member formed by bending and molding a long thin piece formed of a paramagnetic material such as iron or 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, bends and extends to the right side, and the right end (second end) side is a free end. The movable member 25 is flexible, has a free end that can swing, 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 portion of the movable member 25 extending in the left-right direction on the right end side which is the free end. The pressing member 21 presses between the contact portion of the movable magnet 22 and the left end side that is the fixed end. The contact portion of the movable magnet 22 that contacts the movable member 25 can be changed as described above. When the movable member 25 is pressed by the pressing member 21 to bend downward and is released from the pressing, the movable member 25 is biased upward by the magnetic force from the movable magnet 22 and the function as a leaf spring.

The connection member 26 is a member formed by bending and molding a long plate-like body formed of a paramagnetic material such as iron or steel, and is on the left side from the top surface in the accommodation chamber 202 in the housing 20. It is arranged along the inner surface. In the connection member 26, an engagement receiving portion 260 that guides the movement of the movable magnet 22 is formed as a notch on the right end side of the portion provided on the top surface. The engagement receiving portion 260 is formed in a wavy shape and assists in positioning the movable magnet 22. An insertion opening 261 through which the pressing member 21 is inserted is formed on the left side of the engagement receiving portion 260. The connecting member 26 is in physical contact with the movable magnet 22 via the engagement receiving portion 260, and is magnetically connected to the movable magnet 22. As described above, the connection member 26 is magnetically connected to the Hall element 240 of the magnetic field detection unit 24 by the portion arranged along the inner surface on the left side in the accommodation chamber 202. Since the insertion opening 261 of the connecting member 26 has a sufficient size with respect to the pressing member 21, it does not come into contact with 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 in which the pressing member 21 is not pressed by the outside, and FIG. 5B shows a state in which the pressing member 21 is pressed by the outside and moved downward.

As shown in FIG. 5A, when the pressing member 21 is not pressed by 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. In such a situation, the movable magnet 22 formed by using the permanent magnet is magnetically connected to the left side of the hall element 240 via the connecting member 26, and the hall element 240 is connected via the movable member 25. Is magnetically connected to the right side of. Since the movable member 25 and the connecting member 26 are formed of a paramagnetic material, they function as a yoke and allow the magnetic flux emitted from the movable magnet 22 to pass therethrough. Since the upper magnetic pole in which the movable magnet 22 contacts the connecting member 26 and the lower magnetic pole in contact with the movable member 25 have different polarities, for example, through the movable magnet 22, the movable member 25, and the connecting member 26, for example, in FIG. The magnetic flux flowing in the direction indicated by the white arrow passes. Since the movable member 25 and the connecting member 26 are disposed on the left and right sides of the Hall element 240, 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 receives a pressure from the outside, the pressing member 21 is located at the bottom dead center, and the movable member 25 is pressed downward and separated from the movable magnet 22. In such a situation, since the magnetic flux that emerges from the movable magnet 22 and passes through the Hall element 240 is not formed, the magnetic field detectable by the Hall element 240 changes due to 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 an ON signal.

When the user performs a depressing operation on the depressing operation unit 10 of the operating device 1 from the state shown in FIG. 5A, the pressing member 21 of the switch 2 is pressed and moves to the bottom dead center. After transitioning to the state shown, the switch 2 outputs an ON signal to the controller device 1. The pressing operation requires a force that separates the movable member 25 in contact with the movable magnet 22 against the magnetic force, so that the user feels a strong click feeling.

Next, the position adjustment of the movable magnet 22 in the switch 2 described in the present application will be described. 6A and 6B are schematic schematic diagrams showing an example of a dynamic model for the movable magnet 22 and the movable member 25 included in the switch 2 described in the present application. FIG. 6A shows a state in which the movable magnet 22 is moved to a left position near the fixed end, and FIG. 6B shows a state in which the movable magnet 22 is moved to a right position near 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 swings by being pressed in the pressing position and direction shown by the arrow with the fixed end shown by the white circle as the fulcrum. As shown in FIG. 6A, by bringing the movable magnet 22 closer to the fixed end side serving as a fulcrum, the operation load at the time of pressing (hereinafter, referred to as OF (Operation Force)) becomes smaller, and the movable member 25 moves from the start of pressing to the movable member 25. The length of the pressing distance of the pressing member 21 (hereinafter, referred to as PT (Pre Travel)) until the ON signal is output due to the swing becomes short. Further, as shown in FIG. 6B, by bringing the movable magnet 22 close to the free end side which is the point of action, the OF during pressing becomes large and the PT becomes long. In particular, when the distance between the pressing position and the movable magnet 22 becomes long and the OF during pressing becomes large, the degree of bending of the movable member 25 becomes large. PT becomes longer. Conversely speaking, the closer the movable magnet 22 is to the fixed end side, the smaller the degree of bending becomes, and the less the influence of the bending on the PT becomes. In this way, by moving the movable magnet 22, it is possible to adjust the OF and PT and adjust the operational feeling to the user's preference.

The second contact portion 284 is a portion that contacts the swingable 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 accommodation chamber 202 so as to extend in the left-right direction. .. The left end of the movable member 25 is 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 contact portion 283 and the second contact portion 284, and the swing range of the free end is the first contact portion 283 and the free end. It is regulated by the second contact portion 284. The movable member 25 is formed with a biasing portion 250 that functions as a return spring that is punched out in the vicinity of the center and bent in an arc shape. The urging portion 250 has a substantially rectangular shape in a plan view, and is a tongue-shaped piece in which the short side on the right side is connected to the outer frame portion of the movable member 25 and the short side on the left side and both long sides are separated.

As the pressing member 21 moves further downward, the entire movable member 25 is pressed by the pressing member 21 and tries to move downward with the portion locked by the first support portion 281 as the swing axis. Then, since the biasing portion 250 of the movable member 25 swings downward with the portion locked by the second support portion 282 as the swing axis, the entire movable member 25 is inverted so that the first support is performed. It swings with the portion 281 as the swing axis. The free end side of the movable member 25 abuts the first abutting portion 283 due to the oscillation with the first support portion 281 as the oscillation axis. That is, the state illustrated in FIG. 19B is obtained. The movable member 25 collides with the first contact portion 283 with momentum of reversal, and therefore is accompanied by an impact. The user recognizes the change in the sound and the pressing load due to the impact due to the inversion and the collision as the click sound and the click feeling.

When the tip of the bending piece 251 comes into contact with or comes close to the magnetic field detector 24, the magnetic field detectable by the Hall element 240 of the magnetic field detector 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 an ON signal.

As described above, the switch 2 described in the present application includes the 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, it is possible to expand the application range of the switch using a magnet without requiring a mechanical contact. In particular, when a member formed using a paramagnetic material is used, it is possible to improve the magnetic field detection characteristics. Specifically, by forming members such as the movable member 25 and the connecting member 26 using a paramagnetic material, the paramagnetic material functions as a yoke and strengthens the magnetic field, so the magnetic field detection unit 24. It is possible to expect improvement in detection characteristics such as improvement in detection accuracy of the Hall element 240 provided in, and improvement in noise resistance performance.

Further, the switch 2 described in the present application can be configured such that, for example, the contact using the magnetic field detector 24 has both functions of opening and closing a circuit and a click feeling. The switch 2 described in the present application configured to have both functions has a simple structure and is simpler in structure than a switch of a type that uses an optical element and generates a click feeling with a magnet. Since the required cost can be suppressed, it is possible to suppress an increase in manufacturing cost. The switch 2 described in the present application can adjust the click feeling by the magnetic force of the permanent magnet. Further, since the switch 2 described in the present application can adjust the arrangement position of the movable magnet 22, it is possible to adjust the OF and PT to match the operation feeling to the user's preference. Produce the effect.
