A button structure of an input device, including a circuit board, a dome element, and a trigger, is provided. The dome element is disposed on the circuit board, and is electrically conductive and elastic. The trigger is disposed at a center of the dome element, and is electrically insulative and flexible. The trigger has a conductive layer facing the circuit board. The dome element is configured to be pressed to drive the conductive layer of the trigger to abut against a trigger circuit of the circuit board to generate a trigger signal.

A push switch according to the present disclosure includes: a case including a recess; a fixed contact member including a fixed contact disposed in the recess; a movable contact member including a movable contact disposed in the recess; a protective sheet disposed in a first direction from the recess and covering the recess; and a rib disposed on the protective sheet. The protective sheet includes: a pressing portion; a fixed portion fixed to the case; and an intermediate portion located between the pressing portion and the fixed portion as viewed in the first direction. As the pressing portion of the protective sheet is pressed along the first direction, the movable contact member deforms by force received from the protective sheet. The movable contact touches the fixed contact as a result of the deformation of the movable contact member.

An electrical device, such as a flashlight includes an on-off switch that is movable between a maintained actuated position and a maintained unactuated position. The device comprises a body containing an electrical assembly that includes a power source, a switch, and an actuated member, such as a light. The switch includes a first conductor attachable to a first terminal of the power source and the switch member coupled to a second terminal of the power source. The switch member includes a switch portion that has a generally sheet-like portion that is disposed adjacent to the second terminal of the power source. The sheet-like portion includes a deformable central portion surrounded by a retained perimeter. The deformable portion is movable between a maintainable actuated position wherein it contacts the second terminal of the power source, and a maintained unactuated position wherein it is spatially separated from, and not in contact with, the second terminal of power source.

A multipolar switch includes a first electrical contact zone connected to a first electrical circuit, and a second electrical contact zone connected to a second electrical circuit. In addition, a first part made from an electrically conducting material is arranged on and at a distance from the first electrical contact zone, and a second part made from an electrically conducting material is arranged on the first part.

A electrically insulating layer is arranged between the first part and the second part so as to electrically insulate them from one another.

So configured, the first part is configured to be elastically deformed when being mechanically solicited in an actuating direction of the multipolar switch, and the second part is configured to be elastically deformed or be displaced in the actuating direction of the multipolar switch, between a rest configuration and an activated configuration.

A push switch includes: a case including a recess; a fixed contact member including a fixed contact disposed in the recess; a movable contact member including a movable contact disposed in the recess; a protective sheet disposed in a first direction from the recess and covering the recess; and a rib disposed on the protective sheet. The protective sheet includes: a pressing portion; a fixed portion fixed to the case; and an intermediate portion located between the pressing portion and the fixed portion as viewed in the first direction. As the pressing portion of the protective sheet is pressed along the first direction, the movable contact member deforms by force received from the protective sheet. The movable contact touches the fixed contact as a result of the deformation of the movable contact member.

A switch assembly includes a switch and a connector. The switch and the connector are configured to interlock, wherein the switch includes a connection extending at least partially along a center axis of the switch, and the connection is configured to receive at least a part of the connector. The connection may include at least one slot and at least one wedge-shaped groove which is extending from the at least one slot and tapered in a direction of the center axis. The connector may include at least one corresponding wedge-shaped protrusion. The at least one corresponding wedge-shaped protrusion may include a resilient contact blade which can interlock with the at least one wedge-shaped groove.

A switch device includes: a printed circuit board provided with a connector; a rubber sheet; an operating knob; an operating mechanism; an operating mechanism plate; and a housing having a side surface provided with an insertion hole and a bottom surface provided with a discharge hole. The rubber sheet has a connector portion discharge path configured to guide the liquid entering the housing through the insertion hole to the discharge hole. The connector portion discharge path has one end connected to a part of the rubber sheet covering the connector, extends to be inclined from the one end toward the discharge hole provided on the bottom surface, and has the other end formed in a vicinity of the bottom surface and separated from the rubber sheet covering the connector. A gap exists between a lower end portion of the rubber sheet covering the connector and the other end.

A switch device includes: a printed circuit board; a rubber sheet configured to cover the printed circuit board; an operating knob; an operating mechanism; an operating mechanism plate; and a housing having a side surface provided with an insertion hole, and a bottom surface provided with a discharge hole for discharging liquid entering an inside of the housing; and a back cover that is fitted from a back side of the housing and sandwiches an entire periphery of the rubber sheet with a stepped portion formed inside the housing. The printed circuit board is stored in a space between the back cover and the rubber sheet. The discharge hole is located in a lower portion of a space between an inner surface of the housing and the rubber sheet. A bottom portion exists between the discharge hole and the rubber sheet.

An input apparatus includes a base member, an operating member provided so as to be vertically movable with respect to the base member, the operating member being to be pushed down, a circuit board fixed to the base member and provided under the operating member, a push switch provided on a lower surface of the circuit board, and a link mechanism including a rotational member disposed under the circuit board such that a rotation center shaft is rotatably held by the base member, the rotational member pushing the push switch upward by rotating in response to a push-down operation of the operating member.

An electronic device is provided. The electronic device includes a housing having a first surface, a second surface formed parallel to the first surface, and a side surface surrounding a space formed between the first surface and the second surface and a key input device disposed on the first surface and including a plurality of keys. Each of the plurality of keys includes a support member including a conductive contact member, a switch member disposed on one surface of the support member and electrically connected to the conductive contact member of the support member, a key cap, and an elastic member having one surface on which the key cap is disposed, and other surface on which the switch member is disposed at least in part. The elastic member includes a pressing member and at least one elastic bridge connecting the pressing member and a guide region.
