A base of a surge protector, the surge protector comprising a function rotating member (3), and the function rotating member (3) having a remote linkage rod contact wall (3D) and a remote linkage notching (3H), and the base comprising a remote device, and the remote device having at least one remote linkage rod (9), and when the function rotating member (3) is situated at the first position, the remote linkage rod (9) is pressed down by the remote linkage rod contact wall (3D), and when the function rotating member (3) is rotated from the first position to the second position, the function rotating member (3) is rotated from the remote linkage rod contact wall (3D) to the remote linkage notching (3H) with respect to the point of action of the remote linkage rod (9) to release the remote linkage rod (9).

A push switch which can have a small separation distance from a side surface of a mounting board, when it is mounted on the mounting board through a step, is disclosed. The push switch includes a substrate having a first surface on which a first fixed contact point and a second fixed contact point surrounding the first fixed contact point are formed, a second surface located opposite to the first surface, a third surface extending from the second surface to a corner in a direction perpendicular to the first surface, and a fourth surface extending from the corner parallel to the first surface, and a conductive movable contact point having a peripheral edge is in contact with the second fixed contact point, and a center contacted by the first fixed contact point when the movable contact point is pressed, and the corner includes a groove recessed with respect to at least one of the third surface and the fourth surface.

A release mechanism for surge protectors includes a first electrical connection pin (6) soldered with a varistor's second electrode (5B), a function rotating member (3) sheathed on a fixed column (2B and installed between a varistor (5) and a bridge bracket (8), an elastic driving device (4) fixed into an internal box body (2), and a bridge bracket (8) fixed to a second electrical connection pin (7) in the internal box body (2). If the varistor (5) is not released, then the bridge bracket (8) will be passed through a soldering window (3C) and soldered with a varistor's first electrode (5A), or else the elastic driving device (4) will drive the function rotating member (3) to rotate around the fixed column (2B). An arc shield plate (3F) exposed from a failure status indicating area (2N) for triggering a remote linkage rod (9) shields the bridge bracket (8) and electrode (5A).

An electronic device includes a substrate having a top surface, a bottom surface and at least one opening therethrough. The substrate has a circuit. A switch mechanism is mounted to the substrate and is electrically connected to the circuit. The switch mechanism has an actuator configured to activate the switch mechanism. The switch mechanism has a housing holding the actuator and leads extending from the housing. The leads are electrically connected to the circuit. The switch mechanism is mounted to the substrate in the opening such that at least a portion of the housing is positioned below the top surface.

An electronic device includes a tactile switch assembly. The tactile switch assembly includes a tactile switch structure. A grounding structure can be included in an electrostatic discharge path in the tactile switch structure. The grounding structure can result in a shorter electrostatic discharge path that minimizes damage caused by an electrostatic discharge event. Additionally, different grounding connectors are disclosed that can attach to a grounded component in the electronic device and to a tactile switch bracket associated with the tactile switch assembly. The grounding connector provides a grounding connection to the tactile switch bracket.

Embodiments of the present invention provide a circuit structure that allows the use of a single sided Printed Circuit Board (PCB) with a mechanical key structure that has a light emitting element in the middle of the key structure. An LED with pins for protruding through a printed circuit board allows a layout only on the bottom side of the PCB. In one embodiment, the PCB includes at least one low ohm resister forming a bridge for a switch matrix conductor over a perpendicular switch matrix conductor.
