A remote control device may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be configured to be mounted over an installed mechanical switch having a paddle actuator and may include a base and a control unit that is configured to be removably attached to the base. The base may include a frame, a clamp arm, a screw, and/or a sleeve. The clamp arm may be configured to secure the base to a protruding portion of the paddle actuator. The clamp arm may be attached to the frame at a pivot joint. The clamp arm may be configured to pivot about the pivot joint. The pivot joint may be located proximate to an endpoint or a midpoint of the frame.

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.

A pushbutton switch according to one or more embodiment may include a first attachment, an operable portion, and a detector. The first attachment has a loose-fitting hole to loosely receive a locking magnet. The detector includes a switcher that selectively places an attraction magnet or a repulsion magnet at a position facing the locking magnet.

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 keyswitch structure includes a keycap support mechanism and a keycap that is supported by the keycap support mechanism in a vertical direction. The keycap support mechanism includes a base and two supports. The base has two sliding slots. Each sliding slot has an opening in a horizontal direction and an obstruction block at the opening. The horizontal direction is perpendicular to the vertical direction. Each support has a sliding portion and a linkage portion. The sliding portions slide parallel to the horizontal direction in the sliding slots correspondingly. The obstruction block prevents the corresponding sliding portion from disengaging from the corresponding sliding slot. The two linkage portions push against each other in line contact, so that the two supports are mutually driven through the two linkage portions.

A key switch device includes: a key top that includes an operating surface; a pair of link members that is interlocked with each other to move the key top upward and downward; a frame member that includes a leg portion extending downward and a flange portion provided at an end of the leg portion, and pivotably supports the pair of the link members; and a support plate that includes a through hole through which the leg portion and the flange portion penetrate, and a projection portion projecting upwardly from a part of an outer periphery of the through hole toward an inside of the through hole.

A luminous keyswitch includes a keycap having a light-transparent portion, a baseplate, an up-down mechanism with two ends respectively moveably connected to the keycap and the baseplate, a function sheet disposed on or under the baseplate, and a light source disposed on the function sheet within a vertical projection of the keycap and connected by a copper wire to provide a light illuminating the light-transparent portion. The function sheet includes a flexible upper circuit layer having a first contact point, a flexible spacer layer having a hole, and a flexible lower circuit layer having a second copper contact point, a third copper contact point, a first copper wire connected to the second copper contact point, and a second copper wire connected to the third copper contact point. When the keycap is pressed, the first contact point passes through the hole to electrically connect the second and third copper contact points.

A keyswitch structure includes a keycap having a lower surface and an engaging portion protruding from the lower surface, the keycap moving to a lower position when the keycap is pressed, a linking bar coupled with the engaging portion, a distal end of the engaging portion being lower than the linking bar when the keycap moves to the lower position, a baseplate disposed below the keycap, the baseplate having a recessed space corresponding to the engaging portion, and a buffer film disposed on the baseplate, the buffer film substantially extending over the recessed space and having a deformable portion corresponding to the recessed space, wherein when the keycap moves toward the baseplate to the lower position, the distal end of the engaging portion pushes the deformable portion to make the deformable portion extend into the recessed space.

A key switch includes a baseplate, a circuit layer, a keycap and a support rod. The baseplate has a hook and a first through hole neighboring to the hook. The circuit layer includes a first sublayer disposed above the baseplate and having a second through hole, and a second sublayer disposed above the first sublayer and having a third through hole; a portion of the second sublayer extends over the second through hole and forms a first resilient portion; the first resilient portion has four sides, two of which connect to the second sublayer; and the first resilient portion is neighboring to the hook. The keycap is disposed above the baseplate and can move upward and downward in respect to the baseplate. The support rod has a first portion and a second portion; the first portion movably connects to the keycap and the second portion engages the hook.
