The module housing (230) comprises at least one housing stop (332) for abutment against the at least one tappet stop (324) of the key tappet (220) in the rest position of the key tappet (220). Moreover, the key module (110) comprises elastic means (340). The elastic means (340) is configured to bias the key tappet (220) into the rest position in an assembled state of the key module (110).

An electronic device is provided. The electronic device includes a housing, a printed circuit board disposed inside the housing and including a first face and a second face that faces away from the first face, a connection member disposed on the first face and electrically connected to the printed circuit board, a switch member disposed on the first face and at least partially overlaps the connection member when viewed from above the first face, and a button member including an electrically conductive member, and disposed to be capable of operating the switch member. The electrically conductive member is electrically connected to the connection member.

A keyswitch assembly is provided. The keyswitch assembly includes a base plate, at least one pressing mechanism disposed on the base plate, a plurality of elastic members disposed on the base plate, and a keycap covering the at least one pressing mechanism and the plurality of elastic members. In the embodiments, a plurality of elastic members is disposed at equal intervals to support the keycap. By way of such configuration, the user experiences the same or similar hand feeling when pressing any point of the keycap. There is no difference in the pressing feel due for pressing the middle or two ends of the keycap. Meanwhile, the problem of the poor electrical conduction resulted from the deformation of the keycap may be avoided.

A button assembly for an electronic device is disclosed. The button assembly integrates a biometric sensor below a top surface of the button. The button assembly is positioned relative to a secondary display of an electronic device. The secondary display can be positioned relative to a keyboard, such as above a top row of keys of the keyboard.

A lever switch includes a lever main body and a rotary operation element rotatably provided at a tip end portion of the lever main body. The rotary operation element is provided with a light ON switch position at which an instruction to cause head lights and small lights to be on at all times is issued, an automatic light switch position at which an instruction to set an automatic light mode, in which a turned-on state of the head lights and the small lights is controlled based on the intensity of illumination in the vicinity of the vehicle, is issued, and a light OFF switch position at which an instruction to turn the head lights off is issued, the light ON switch position, the automatic light switch position, and the light OFF switch position being arranged in an order along a rotation direction.

A button restoring mechanism of an electronic device includes a housing, an adjustment button mounted on the housing, a bracket, and an elastic member. One side of the adjustment button protrudes within the housing. The bracket latches with the adjustment button. One end of the elastic member is fixed to one side of the bracket, and a second end of the elastic member abuts against a second side of the bracket. An elastic force of the elastic member drives the second side of the bracket to abut against a switch button within the housing.

A switch button module is provided. The switch button module is adapted to be disposed in an electronic device. The electronic device includes a housing, a circuit board, and a switch element. The circuit board is disposed in the housing. The switch element is disposed on the circuit board. The switch button module includes a mounting base, a connection rod, and a button unit. The mounting base is affixed to the housing, wherein the mounting base is located between an edge of the circuit board and the housing. The connection rod pivots on the mounting base. The connection rod rotates between a first orientation and a second orientation.

A foot pedal for controlling a medical device, in particular a dental device, including a housing with a housing base, a cover element which is mounted so as to be vertically displaceable with respect to the housing base along an actuating direction and so as to be inclinable with respect to the housing base, a first switch for initiating a first functionality on the medical device and a second switch for initiating a second functionality on the medical device, and an actuating device which is vertically displaceable along the actuating direction and which actuates the first switch during a movement in the actuating direction within a first height offset section and actuates the second switch within a second height offset section, the actuating device being configured in such a way, in that it is in a first state in the first height offset section and in a second state in the second height offset section, where the foot pedal being configured such that, at a predeterminable angle of inclination of the cover element, the actuating device is always arranged within the first height offset section.
