An illuminated glass keycap having a glyph diffuser layer that may diffuse light through a glyph window opened in a background layer. The background layer may be opaque and the glyph window may be transparent. The keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the keycap, around the perimeter of the keycap, and/or through the background layer.

A relay includes a housing, a fixed terminal, a screw receiving member, and at least one female screw member. The fixed terminal has a plate shape. The fixed terminal includes a fastening portion having at least one screw insertion hole. The fastening portion is exposed from the housing to an outside and is screwed to an external terminal. The screw receiving member overlaps with the fastening portion in a penetrating direction of the at least one screw insertion hole and is provided in proximity to the fastening portion. The at least one female screw member is provided integrally with or separately from the screw receiving member and is prevented from rotating by the screw receiving member.

An electronic device and a wearable electronic device are provided in implementations of the disclosure. The electronic device includes a housing frame, a button assembly, and a circuit assembly. The housing frame has an inner cavity and a first through hole. The first through hole communicates with the inner cavity and an external space outside the housing frame. The button assembly includes a first conductive member and a second conductive member. The first conductive member is connected to the housing frame and at least partially in the external space. The second conductive member is at least partially in the first through hole. The first conductive member elastically abuts against the second conductive member, so that the first conductive member is in electrical communication with the second conductive member. The circuit assembly is disposed in the inner cavity.

A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.

A wall box may provide adjustable support for a control device, such as a keypad, to allow for level alignment of the control device when mounted to the wall box. The wall box may have an adjustable support frame to which the control device may be mounted. When the control device is mounted to the support frame of the wall box, the support frame may be rotated to adjust the alignment of the control device. In addition, the wall box may comprise one or more projections configured to be received in respective detents in notched surfaces of the control device to allow for adjustment of the alignment of the control device. Further, the wall box may have a modular assembly and may be constructed from a central portion and two side portions at the time of installation of the wall box.
