A keyswitch includes a board having a first magnetic portion and a pivot portion, a cap, a switch, and a support device including a first support member having first and second bodies connected to each other via an elastic connection arm. The first body has first and second end portions connected to the cap and the pivot portion respectively. The second body has a second magnetic portion and a triggering portion. A U-shaped slot is formed around the triggering portion to make the triggering portion form an elastic cantilever arm extending from the second body. When the cap is pressed to make the second magnetic portion away from the first magnetic portion at a specific distance, the triggering portion triggers the switch. When the cap is released, a magnetic force between the first and second magnetic portions drives the second magnetic portion to approach the first magnetic portion.

A push-button starter for use with an outdoor power equipment unit. In one embodiment, the starter includes a housing defining an opening to receive a removable button, and a peripheral edge surrounding the opening. The peripheral edge may define two scalloped areas such that two opposite sides of a head portion of the button are exposed and accessible when the button is in a neutral position within the housing while remaining sides of the head portion are enclosed within the housing. Moreover, the opening and the head portion may be configured to control an orientation of the button relative to the housing, and further prevent rotation of the button relative to the housing.

An illuminated keyswitch includes a keycap, a pair of frames adapted to support the keycap in an up-down movement, the pair of frames disposed corresponding to each other and substantially rotatably coupled to each other to define an inner space under the keycap, a pair of elastic members connecting the pair of frames to be located at two opposite sides of the inner space, respectively, and an illumination light source disposed between the pair of elastic members in the inner space and adapted to provide an illumination light. During the up-down movement of the keycap, a vertical projection of the pair of frames surrounds the inner space without interfering therewith, so the illumination light passes the inner space to illuminate the keycap.

A key structure includes a supporting plate, a keycap, a scissors-type connecting element, a movable element and a coupling structure. The keycap is disposed over the supporting plate. The coupling structure is connected with the scissors-type connecting element and the movable element. For operating the key structure, the cooperation of the movable element and the coupling structure allows the keycap to be at a higher first height. Consequently, the tactile feel of depressing the key structure is enhanced. Moreover, the cooperation of the movable element and the coupling structure can lower the height of the keycap. Consequently, the key structure has a slim appearance.

A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

A key structure includes a circuit board, a keycap, an elastic member and a metal member. The keycap has a bottom facing the circuit board. The elastic member is disposed between the circuit board and the keycap. The elastic member includes a dome portion, a hollow portion, and a contact pillar. The dome portion touches the bottom of the keycap. The hollow portion is located inside of the dome portion. The contact pillar is located in the hollow portion, and the contact pillar extends from the dome portion to the circuit board. The metal member covers the outside of the contact pillar. The metal member comprises a trigger portion, and the trigger portion is a convex portion extending toward the circuit board.

A composite sheet metal component for an automobile comprises an inner metal sheet, an outer metal sheet and an intermediate polymer sheet arranged between the inner and the outer metal sheet. The intermediate polymer sheet comprises a semiconductor device and the outer metal sheet comprises at least one functional area.
