| PROBLEM TO BE SOLVED: To provide high contact reliability and to improve operation feeling in an operation, by providing a fixed contact and a dome-like movable contact disposed on the fixed contact, and forming a protrusion contactable/separatable from the fixed contact in a part other than a dome-like top on the inner surface side of the movable contact. SOLUTION: A plurality of protrusions 5c are on an annular line in a part other than a dome-like top 5a on the inner surface side of the movable contact 5. When a stem 6 is pressed down, these protrusions 5c come into contact with a fixed contact 3, and therefore, the fixed contact 3 comes into contact with a movable contact 5 in a place without dust having tendency to accumulate at a central part 3a of the fixed contact 3. Therefore, this is stable in contact comparing with a structure where a top 5a directly comes into contact with the central part 3a of the fixed contact 3, and contact reliability is improved. Because the dome-like top 5a positioned inside the protrusion 5c also becomes movable during inversion, operation feeling during an operation does not exert bad effect.

| A pressure responsive, variable resistance, analog switch has first and second conductors interleaved in spaced-apart relationship and disposed on a base member. An insulative spacer ring is positioned around and rises above the first and second conductors. A resilient cover sheet is attached to the top of the insulative spacer ring in spaced relationship over the conductors to define an enclosure between the resilient cover sheet and the base member. A pressure sensitive resistive conductor composition is disposed on the resilient cover sheet or on the conductors in the enclosure to interconnect a resistance between the first and second conductors when the resilient cover sheet is depressed against the conductors. The amount of resistance so interconnected varies inversely to the amount of pressure exerted. | ||||||

| A pressure transducer device particularly useful in an electronic musical instrument includes a flexible base folded to define upper and lower flexible base portions, a donut-shaped first spacer between the upper and lower base portions and a resiliently deformable diaphragm attached about its periphery to the upper flexible base portion with a second donut-shaped spacer therebetween. A center region of the diaphragm laterally spaced from the second spacer is adhesively attached to a central region of the upper flexible base portion so that the upper flexible base portion moves inwardly and outwardly in response to the movement of the diaphragm. A pair of conductors are disposed on the folded flexible base member to face one another. A pressure responsive composition disposed over the conductors provides a contact resistance across the pair of conductors which varies inversely with the amount of pressure force exerted against the diaphragm. The upper flexible base portion may be attached between the first and second spacers about its entire periphery or at a small hinge region with the upper base portion being a flap movable about the hinge region in the region surrounded by the first spacer. | ||||||

| A multi-function touch switch apparatus has a first semiconductor composition layer disposed on top of a first conductor layer which is affixed to a first base member. A second semiconductor composition layer opposing the first semiconductor in spaced relationship thereto is disposed on a second conductor layer which is itself disposed on the bottom surface of a second support member. A third conductor layer is also disposed on the top surface of the second support member in opposing spaced-apart relationship to a fourth conductor layer disposed on the bottom surface of a third support member. The second and third support members and the affixed conductor layers and semiconductor layers are resiliently deformable in a transverse axis in response to a transverse touch force to thereby cause electrical contact between the second and third conductor layers to provide a closed switch and the first and second semiconductor layers to provide a closed switch in series with a pressure sensitive resistance. | ||||||

| PROBLEM TO BE SOLVED: To eliminate poor contacting condition in a mirror switch having a conter-contact without changing the shape of a die by introducing such a configuration that burr of a stationary contact touches a movable contact. SOLUTION: A stationary contact 15a is composed of a pair of stationary electrodes 17a and 18a and manufactured through insert molding. In insert molding, burrs 20a formed on the stationary electrodes 17a and 18a are oriented as directed to a rubber electrode 22a, so that no film of resin 24 is formed on the surfaces of the stationary electrodes 17a and 18a. Accordingly when a mirror angle adjusting button is pushed, the rubber electrode 22a touches the tip of the burr 20a certainly. Further there is no need to prepare a die for insert molding equipped with a projection for preventing formation of a film of resin 24, but a conventional die for insert molding may be used which eliminates necessity for alteration of the design.

| PURPOSE: To make setting to a molding die easy and enhance adhesion between a moving contact part and a rubber sheet. CONSTITUTION: A fixed contact 2 is formed on a printed circuit board 1, and an operating part 4 is formed in a rubber sheet 3 arranged on the printed circuit board 1 so as to cover the fixed contact 2. The operating part 4 is bent and deformed by pushing operation of a push button, and a moving contact plate 7 formed in the operating part 4 is brought into contact with the fixed contact 2. Minor projections 8 are formed on the inside and outside of the moving contact plate 7. By forming the minor projections 8 on the inside and outside, selection of the direction of the moving contact in setting is made unnecessary when the rubber sheet 3 is formed, and regarding the operating part 4 side, the contact surface of the moving contact 7 is increased to increase bonding strength. | ||||||

| PROBLEMS In a contact member provided with a plurality of protrusions in a curved portion and a switch device using the contact member, deterioration of an operating sensation is caused not to occur even though a pressing point is deviated from the center. SOLVING MEANS A dome-shaped curved portion 12 is formed in a contact member 10 formed of a metal leaf spring material, and three protrusions 13a, 13b, and 13c protrude toward a substrate at the periphery of a center O1. The extension direction of the leaf spring material that forms the contact member 10 is the X direction. The protrusions 13b and 13c are disposed at positions where the circular contours thereof do not overlap with a vertical center line Ox extending in the extension direction. Therefore, the positions of the protrusions may be displaced with respect to a direction in which an operating sensation is deteriorated due to the influence of the extension direction of the material, so that when a position distant from the center 01 is pressed, an area where the operating sensation is not deteriorated may be enlarged in a wide range in the X direction and the Y direction. | ||||||

A pushbutton switch (1) includes a fixed contact portion (3) provided on a substrate (2) and an elastically deformable movable contact portion (4) provided in opposition to a surface of the fixed contact portion, the movable contact portion being configured as a dome-like portion forming a greater gap relative to the surface of the fixed contact portion at a center portion of the surface than at a peripheral portion of the surface. The fixed contact portion (3) includes, at a center portion on the surface thereof, a surface-devoid portion (5) forming a contact edge (30) in cooperation with the surface, and the movable contact portion (4) includes a projection (6) projecting toward the surface-devoid portion of the fixed contact portion. When a press force is applied to the movable contact portion (4), the movable contact portion is elastically deformed against resilience thereof toward the contact edge (30) to come into contact with the edge or an area adjacent thereto. When the press force is released, the movable contact portion (4) is elastically restored to move its projection (6) away from the contact edge (30) or the adjacent area. |
