A keyswitch includes a cap, first and second support members slidably connected to the cap and opposite to each other, and first and second blocks formed on the cap. The cap is movable between a non-pressed position and a pressed position. The first support member abuts against the first block when the cap is located at the non-pressed position. The first block moves away from the first support member at a first gap when the cap moves downward from the non-pressed position. The first support member abuts against the cap when the cap is located at the non-pressed position, and abuts against the second block when the cap continues moving downward to the pressed position.

A push switch includes a housing including a bottom wall and a side wall, the housing extending in a first axis direction and a second axis direction in a plan view, and a fixed contact member configured to come into contact with a movable contact member, the fixed contact member being embedded in the bottom wall of the housing by insert molding, wherein the fixed contact member includes: a first terminal exposed to an outside from a first end portion in the first axis direction of the housing; and first extension portions, constituting a pair, that are both ends of the first terminal in the second axis direction, the first extension portions being bent upward and being embedded in the bottom wall or the side wall of the housing, or in both the bottom wall and the side wall of the housing, by the insert molding.

An activation assembly is configured to be assembled with a substrate and a keycap. The activation assembly includes a flexible guiding component and an elastic component. The flexible guiding component includes a covering portion, a first contact portion, and a second contact portion. The covering portion has a plurality of openings. The covering portion is configured to be mounted on the substrate. The first contact portion and the second contact portion are respectively located at two opposite sides of the covering portion. The elastic component includes a coupling portion and a plurality of support portions. The coupling portion is connected to the covering portion. The support portions are connected to the coupling portion and are respectively located in the openings.

A control device includes a button assembly having one or more buttons and a button carrier that includes a plurality of resilient, independently deflectable spring arms. The control device may be configured as a wall-mounted keypad to control a load control device, or as a thermostat to control a temperature regulation appliance. The button carrier may be configured to prevent interference between the buttons during operation of the control device. The button assembly may be captured between a faceplate of the control device and a housing that is attached to a rear side of the faceplate. The control device may include one or more button retainers that are attached to the buttons and that are configured to align respective outer surfaces of the buttons relative to each other, and relative to the faceplate of the control device, when the buttons are in respective rest positions.

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 control device includes a button assembly having one or more buttons and a button carrier that includes a plurality of resilient, independently deflectable spring arms. The control device may be configured as a wall-mounted keypad to control a load control device, or as a thermostat to control a temperature regulation appliance. The button carrier may be configured to prevent interference between the buttons during operation of the control device. The button assembly may be captured between a faceplate of the control device and a housing that is attached to a rear side of the faceplate. The control device may include one or more button retainers that are attached to the buttons and that are configured to align respective outer surfaces of the buttons relative to each other, and relative to the faceplate of the control device, when the buttons are in respective rest positions.

An electrical switch (100) includes an insulative housing (110) forming a receiving space therein, a fixed contact set (121, 122) retained in the housing (110), a movable contact set (131, 132) located above the fixed contact set (121, 122), and a cover (140) mounted upon the housing, wherein the moveable contact set (131, 132) further includes at least three outwardly and downwardly extending protrusions (133) on a periphery at equal intervals so as to support up-and-down movement of the moveable contact set (131, 132) during operation with a superior manual feeling.

A slim-type keyboard includes a first flexible layer, a pressed frame and a circuit board assembly. The first flexible layer includes plural pressed regions. The pressed frame includes plural cantilever strips. The circuit board assembly includes plural dome switches. The plural cantilever strips are covered by the first flexible layer. The pressed regions are aligned with the cantilever strips and the dome switches, respectively. When one of the pressed regions is pressed, the cantilever strip is pushed down to trigger the corresponding dome switch. Each cantilever strip includes a U-shaped groove and a suspension end. The U-shaped groove opens to the suspension end. Consequently, the tactile feel of pressing the cantilever strip is improved.

A keyboard switch, including a base; a static contact; a moving contact; an upper cover; a button configured to control the contact of the static contact and the moving contact; and a reset spring configured to control the reset of the button.

Fabric enclosure backlighting techniques are described. In one or more implementations, one or more translucent portions are formed within a plurality of layers of a fabric enclosure assembly. In one approach, regions within one or multiple layers are laser etched to form the translucent portions within the fabric enclosure assembly. A light source is then arranged to selectively transmit light through the layers via the translucent portions to provide backlight for one or more elements integrated with fabric enclosure assembly. The one or more elements may include representations of input keys and/or graphics associated with the fabric enclosure assembly. The backlight may be used to view the one or more elements in low light and/or provide backlight effects such as borders, side lighting, labels, and so forth.
