A changeover switch for medium voltage switchgear is provided. The changeover switch includes a first terminal body, a second terminal body, and two elongate pole bodies. The two elongate pole bodies are arranged parallel to each other and rotatably arranged with first ends on opposite sides of, and in direct contact with the first terminal body around a rotation axis. The two elongate pole bodies are rotatable between an open position and a closed position. The second ends of the two elongate pole bodies are positioned in direct contact with opposite sides of the second terminal body. The changeover switch further includes one or more springs arranged between the two elongate pole bodies to urge the two elongate pole bodies towards each other.

An AC disconnect switch with integral surge protection. The intrinsic pullout head of the AC disconnect switch embodies a surge protection device, thereby eliminating the need for an extrinsic surge protection device.

The invention provides a switch device including a shell, an operating member, a spring, a movable conductor, a first pin, a second pin, two resistors, and two connecting conductors. The operating member is partially exposed out of the shell, and the movable conductor is displaced when the operating member is operated. One side of the shell is provided with the first pin and the spring, another side is provided with the second pin. The resistors are connected with the second pin and have different resistance values. The connecting conductors are arranged between the two pins. The first pin contacts with the movable conductor. The connecting conductors without disposal of any crossover part therebetween and respectively connected with the resistors. The connecting conductors are arranged at intervals along a displacement path of the movable conductor which contacted one connecting conductor before and after displacement and forming two conductive paths.

A wireless switch includes a switch body, a push button connected to the switch body in a state of being movable along an approaching/separating direction between a non-operating position and an operating position, a signal output device accommodated in the switch body and configured to output a switch signal in response to a movement of the push button from the non-operating position to the operating position, and a restriction member that restricts the movement of the push button from the non-operating position to the operation position when the push button is located at the non-operating position.

The present invention relates to an operation device which can be easily installed on a vehicle door, and a vehicle door comprising the operation device. An operation device of the present invention comprises: a gripper provided on an inner surface of a door of a vehicle; an operation interface provided on an inner side surface of the gripper for receiving an operation input entered by an occupant to operate at least one in-vehicle device; a first sensor provided on an outer side surface of the gripper for detecting a finger of the occupant; a second sensor provided on at least one of the inner side surface and an upper surface of the gripper for detecting a finger of the occupant; and a controller connected to the operation interface, the first sensor, the second sensor, and the at least one in-vehicle device. The controller controls the at least one in-vehicle device based on a signal from the operation interface when both the first sensor and the second sensor detect the occupant, and prohibits the at least one in-vehicle device from being controlled based on a signal from the operation interface when at least one of the first sensor and the second sensor does not detect the occupant.

A switch assembly is configured to be mounted to a lower cover of the junction box assembly. The switch assembly includes a holder, the holder is configured to removably coupled to the lower cover. The holder includes a pocket. The switch assembly further includes a switch. The hook is configured to engage the lower cover and is dimensioned to be seated within the pocket of the holder. The switch includes a hook. The hook is configured to pull the switch towards the lower cover so as to pinch the holder between the lower cover and the switch. Accordingly, the hook presses the switch against a bottom surface of the lower cover so as to eliminate a rattle when the switch is held in suspension beneath the lower cover of the junction box assembly.

A dimmer switch configured to be controlled by a remote controller is provided. The dimmer switch comprises a supporting portion for supporting the remote controller, and the remote controller is selectively matched in the supporting portion. A first surface of the supporting portion that is configured to be in contact with the remote controller is disposed with a first electric connection member configured to be in data communication with the remote controller, and a second surface of the remote controller that is configured to be in contact with the first surface of the dimmer switch is disposed with a second electric connection member configured to be in data communication with the dimmer switch. When the remote controller is matched with the supporting portion of the dimmer switch, the first electric connection member of the dimmer switch is in contact with the second electric connection member of the remote controller.
