The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.

An actuation assembly for a double throw switch is disclosed. The assembly includes a pair of links. A distal end (D) of each of the pair of links is connectable to a first switch and a second switch of the double throw switch. A proximal end (P) of each of the pair of links includes a protuberance. Further, the assembly includes a drive disc securable to a wall of the double throw switch. The drive disc is defined with a plurality of slots of pre-defined profile. Each of the plurality of slots is structured to accommodate and guide the protuberance extending from a corresponding link of the pair of links. A lever arm is connectable to the drive disc and is operable to at least one of a first position, a neutral position, and a second position.

A press-type input device includes a first pressing member, a second pressing member, a base, and a holding member. The first pressing member has a pressure receiving surface and a first axis and is tiltable around the first axis. The second pressing member has a second axis and is tiltable around the second axis. The base includes a detection unit configured to detect a tilt of the second pressing member. The holding member is configured to hold, together with the base, the first pressing member and the second pressing member. A location of at least one of the first axis or the second axis is variable in accordance with a pushed location on the pressure receiving surface. When viewed in a direction vertical to the pressure receiving surface, the second axis and the detection unit do not overlap each other.

A modular transfer switch (22) and actuator (20) wherein multiple transfer switches are connectable in linear arrangement with the actuator such that the actuator controls the position of all of the transfer switches. Each of the transfer switches (22) includes a contact assembly (48) that converts over-rotation of the drive linkage (26) in the transfer switch to added pressure between the load contacts and the power contacts in the contact assembly.

An electric power tool has a tool receptacle and a tool housing in which a drive motor for driving the tool receptacle is arranged. The drive motor is switchable on and off via an electric switch. An operating part for indirectly actuating the switch is arranged on the tool housing and extends approximately parallel to a longitudinal axis of the tool housing. The operating part is lever-like and is pivotably arranged on the tool housing. An actuating member of the switch is displaceable approximately parallel to the longitudinal axis by an actuating force that acts on the operating part approximately perpendicularly to the longitudinal axis. The drive motor is switched on by the actuating force acting on the operating part against a restoring force of the switch, and the drive motor is switched off automatically, via the restoring force, when the operating part is released by a user.
