An ON/OFF switch arrangement is for a display screen pivotably mounted within a motor vehicle. The arrangement includes a mounting bracket retaining the display screen and pivotably attached to the motor vehicle such that the mounting bracket may be pivoted about an axis. A switch assembly includes a rotor attached to the mounting bracket. A contactor is attached to the rotor. A base is attached to the motor vehicle such that the rotor and the contactor rotate about the axis relative to the base when the mounting bracket is pivoted. The base has two spaced apart electrical contacts. The contactor electrically interconnects the two contacts within a first range of rotational positions of the rotor, and the contactor does not interconnect the two contacts within a second range of rotational positions of the rotor.

A rotor rotator and rotor system for a multi-pole electrical rotary battery switch having a rotor with a top surface and a bottom surface and a key insert opening on the top surface. One or two bus plate connectors are held in chambers on the bottom surface of the rotor. A rotor rotator has a servo motor with a motor gear in the rotor rotator, a switch nob connector at a top end of the rotor rotator, and a rotor key shaft at a bottom end of the rotor rotator which inserts into the key insert opening of the rotor. A programmable printed circuit board with a processor and memory are positioned around the rotor rotator and provide electrical current to the servo motor. Electrical connector poles provide electrical current to the printed circuit board by means of electrical conducting springs. The switch operates both automatically and manually.

A cable enclosure includes a housing defining an opening through which an interior of the housing is accessible. An end plate is releasably secured to the housing to cover the opening such that the interior of the housing is not accessible. The end plate includes a first conductive leg in electrical communication with a first cable within the housing. The end plate also includes a second conductive leg in electrical communication with a second cable within the housing. The end plate further includes a conductive member movable between a first position and a second position. When in the first position, the conductive member is in contact with the first conductive leg and the second conductive leg. When in the second position, the conductive member is not in contact with at least one of the first conductive leg or the second conductive leg.

The disclosure describes a switch extension device and method of installing such a device on a unit of electrical equipment with a closable housing containing a switch and electrically charged components, such as a transformer with a rotary oil safety switch inside the transformer terminal cabinet. The device includes a switch coupling member for mechanically manipulating a switch between at least a first switch position and a second switch position. The switch is disposed inside the closed housing containing components that are electrically charged when the switch is in the first position and not electrically charged when the switch is in the second position. The device also has an extension member with an external portion that extends outside of the closed housing for access by the user without opening the closed housing. Physical manipulation of the external portion of the extension member is mechanically translated to the switch coupling member for mechanically manipulating the switch between at least the first switch position and the second switch position.

An isolation switch includes a plurality of posts connectable to trace lines and/or a ground line at one side of a housing of the switch. Inside the switch, a conducting contact plate can be moved between a bonded mode, where each of the terminals are interconnected, and a test mode, where the contact plate moves, within the housing, electrically isolating each post and allowing for discrete locating.

Switches with integrated overcurrent protection elements are described. The overcurrent protection elements can include a bimetallic structure which is configured to move between a first shape and a second shape in response to heating. The overcurrent protection element can be rotationally coupled to a rotary knob in some embodiments. In other embodiments, the overcurrent protection element can be fixed, and the rotary knob can be connected to one or more rotatable conductive structures within the rotary switch.
