Key assemblies having a foldable stabilizer are disclosed. The stabilizer can be positioned under a keycap to help guide the keycap and limit rotation or movement when the key is pressed. The stabilizer can have a pointed-star shape with multiple folding axes and can have multiple points of connection or linkage to the keycap or other surrounding components. The stabilizer can unfold or flatten as the keycap is pressed and can fold as the keycap is raised.

A push switch including a pressing member, a movable contact, an interposed member, a first fixed contact, and a second fixed contact is provided. The pressing member includes a pressing portion configured to be pressed, and includes an elastically deformable peripheral wall portion having a lower end portion and extending downward and outward from the outer periphery of the pressing portion. The movable contact has a dome shape and is disposed below the pressing member. The interposed member is disposed between the pressing member and the movable contact, and is configured to press the movable contact by receiving and being pressed by the lower end portion of the peripheral wall portion of the pressing member. The lower end portion of the peripheral wall portion of the pressing member presses the interposed member while the peripheral wall portion is subjected to elastic deformation in response to the pressing portion being pressed.

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 input device is characterized in that in a first stroke region in which an operation panel is pushed during a touch operation, a first reaction force that occurs by pushing the operation panel is generated by the first elastic portion. In a second stroke region including a stroke longer than in the first stroke region and a stroke for performing a push operation, a second reaction force that occurs by pushing the operation panel is a resultant force generated by a first elastic portion and the push switch. In the vicinity of a boundary between the first stroke region and the second stroke region, the amount of change in the first reaction force with respect to a stroke length is less than the amount of change in the second reaction force with respect to a stroke length.

Implementations of a multi-pole dome switch configured to simultaneously, or nearly simultaneously, close or open two separate circuits are provided. In some implementations, a multi-pole dome switch may comprise a tactile metal dome and a conductive insert that are separated by an insulator. In some implementations, when the dome is depressed, the dome and the conductive insert are configured to simultaneously, or nearly simultaneously, make conductive contact with two traces of a first circuit and two traces of a second circuit, respectively, positioned thereunder on a PCB. In this way, the multi-pole dome switch is able to simultaneously, or nearly simultaneously, close two separate circuits. Succinctly put, in some implementations, the multi-pole dome switch may be configured to act as a double-pole, double-throw switch.
