An input device configured to more accurately detect movement of an operation part is provided. An input device includes a fixed electrode, a reference electrode, an operation part, and a moving electrode. The fixed electrode and the reference electrode are separate from each other on a substrate. The operation part is movable with respect to the substrate. The moving electrode faces the fixed electrode and is configured to move together with the operation part. The moving electrode 15 moves together with the operation part to enter either a connected state of being electrically connected to the reference electrode or a non-connected state of not being electrically connected to the reference electrode.

An exemplary working cylinder for a drive of an electric circuit breaker includes a base that includes a cylinder head and a cylinder body that are connected to one another. Additional components are fastened to the cylinder head as a core piece of the drive, and a thrust ring is guided on an outer surface of the cylinder body. The thrust ring compresses mechanical springs in the mechanical resilient energy storage device by way of a storage piston in a storage module.

A side key structure of an electronic device includes a housing, a flexible circuit board, and a side key. The housing defines a receiving groove. The flexible circuit board includes a key switch. The side key includes a main key body, a fastener, and a pressing portion. The flexible circuit board is mounted on a sidewall of the receiving groove. The pressing portion and the fastener are arranged on a same side of the main key body. The main key body is partially received in the receiving groove. The fastener and the pressing portion pass through a second sidewall of the receiving groove. The fastener is mounted within the receiving groove. The main key body is configured to be pressed to cause the pressing portion to press the key switch to activate the key switch.

A switching device includes a switch and an actuating element. The actuating element for a switch includes a U-shaped actuating section. The actuating section includes two different arms with different lengths. The long arm is configured to transfer force to a button of the switch and a free end of the long arm is configured for holding the actuating element. The short arm is configured for the force input and is arranged aligned obliquely to the long arm.

An electronic device controller assembly for ergonomic dual-handed control of the electronic device includes a housing. At least one circuit board is positioned in the housing. The at least one circuit board is configured to selectively and operationally couple to the electronic device. Each of a pair of sticks is pivotally coupled to and extends between the upper face of the housing and a bottom of a respective plate. Each plate is configured to position a respective hand of a user. A plurality of first buttons is coupled to the plates. The sticks and the first buttons are operationally coupled to the at least one circuit board. Each first button is configured to be depressed to selectively control a respective function of the electronic device. Each plate is positioned to compel an associated stick to pivot relative to the housing to signal a directional movement.

A universal circuit board compatible for a mechanical keyswitch and an optical keyswitch includes a main body, a plurality of conductive terminals and an opening structure. The main body has a first surface and a second surface opposite to each other. The plurality of conductive terminals is disposed on the first surface of the main body. The opening structure is formed on the main body and pierces through the first surface and the second surface. The opening structure can be inserted by an axle body of the mechanical keyswitch or be an optical transmission channel of the optical keyswitch.
