What is presented is a key module with a cover element and a tappet having a cam nose, wherein the tappet is supported to be movable along a movement axis by the cover element, wherein the tappet has a cylindrical keycap supporting portion in a passage area in which it projects through the cover element and has at least one rib on a guiding portion adjacent to the an keycap supporting portion on an outside. Furthermore, the key module includes a contactor unit formed and arranged to be taken along by the cam nose, and a contact piece formed and arranged for establishing electric contact with the contact nose. Moreover, the key module has a housing element for accommodating the contact piece, the contactor unit and the tappet, wherein the housing element has, for accommodating the guiding portion of the tappet, at least one accommodating bowl with at least one recess for accommodating the at least one rib of the tappet.

A remote controlled miniature circuit breaker includes a helical gear that engages with mating teeth of a slider plate coupled to main contacts of the circuit breaker, the helical gear including a flat portion to allow the sliding plate to slide past the helical gear. A unidirectional motor responds to an external signal to drive the helical gear while engaging the mating teeth of the slider plate, thereby moving the slider plate to close the main contacts. The motor is configured to respond to an external signal to resume the unidirectional rotation of the helical gear to position the flat portion of the gear to allow the slider plate to slide past the helical gear and contact a kicker lever to thereby open the main contacts. A trip lever pivotally mounted separately from the kicker lever, pushes the kicker lever to open the main contacts in a trip operation.

A switch panel for an aircraft includes a cover and aback plate. A distance from the cover to the back plate is a thickness of the switch panel. In some cases, the thickness is less than about 9.525 mm. A button assembly for a switch panel for an aircraft includes a button base, a button retainer, and a lens. The button base includes a bottom end, a base side, and a transition portion between the bottom end and the base side. In certain cases, the transition portion of the button base is beveled or radiused with a sloped or concave shape.

Low-profile keysets and input devices having such low-profile keysets are described. In one example, the input device includes a support structure having a first and second surface; a bezel having a first and second surface, wherein the first surface of the bezel is adjacent to the first surface of the support structure, and the bezel comprises at least one opening; at least one key cap positioned within the at least one opening of the bezel, wherein each key cap is configured to move between a first and second position to trigger a function of the input device; and a fabric cover layer positioned adjacent to the second surface of the bezel, such that the bezel and the at least one key cap are positioned between the fabric cover layer and the support structure, the fabric cover layer is only adhered to the second surface of the bezel.

A remote controlled miniature circuit breaker includes a helical gear that engages with mating teeth of a slider plate coupled to main contacts of the circuit breaker, the helical gear including a flat portion to allow the sliding plate to slide past the helical gear. A unidirectional motor responds to an external signal to drive the helical gear while engaging the mating teeth of the slider plate, thereby moving the slider plate to close the main contacts. The motor is configured to respond to an external signal to resume the unidirectional rotation of the helical gear to position the flat portion of the gear to allow the slider plate to slide past the helical gear and contact a kicker lever to thereby open the main contacts. A trip lever pivotally mounted separately from the kicker lever, pushes the kicker lever to open the main contacts in a trip operation.

The present disclosure provides a membrane switch, a key, and a keyboard. The membrane switch includes: a flexible substrate; a switch trace layer, disposed on a front surface of the flexible substrate, and comprising a plurality of conductive contacts that not in contact with each other; a flexible key, covering the switch trace layer, a press cavity being defined between an inner wall of the flexible key and the flexible substrate; and a conductor, disposed in the press cavity, and configured to be connected to the plurality of conductive contacts in response to the flexible key being pressed, such that the switch trace layer is conducted. The membrane switch, the key, and the keyboard according to the present disclosure have a compact structure, a high integration degree, and a small thickness, and thus accommodate demands of the market on lightening and thinning.

A straight-through three-in-one light-emitting key core module comprising a support structure, an insulating layer, a circuit layer, a spacer layer, an elastic conducting member, an LED light and a keycap, wherein the insulating layer is arranged on the support structure, the circuit layer is arranged on the insulating layer, and the spacer layer is arranged above the insulating layer, a first through hole is opened in the spacer layer at a position corresponding to the keycap, an elastic conducting member is arranged at a position corresponding to the first through hole, an LED light is arranged on the circuit layer and is arranged corresponding to the keycap, a second through hole is opened on the spacer layer corresponding to a position of the LED light, the LED light is arranged in the second through hole, and the keycap is arranged above the elastic conducting member.

A keyboard device includes plural key structures. Each key structure includes a base plate, a keycap, a membrane circuit board, a connecting member and an elastic element. The keycap includes a pressing post. The membrane circuit board is arranged between the base plate and the keycap. The connecting member is penetrated through the membrane circuit board and connected between the keycap and the base plate. The keycap is movable upwardly or downwardly relative to the membrane circuit board. The elastic element is arranged between the keycap and the membrane circuit board. The elastic element includes a resilience piece and plural supporting ribs. The plural supporting ribs are arranged between the resilience piece and the keycap. The plural supporting ribs are contacted with the pressing post of the keycap. Consequently, there is a gap between the pressing post and the resilience piece.
