A fuse is at least partially located between a first load relay and a first charging relay, and an electric current detector is at least partially located between a second load relay and a second charging relay. The electric current detector is in contact with an insulating layer. As viewed from the side, the fuse is located below the electric current detector. The fuse is not in contact with the electric current detector.

A coupler between an activator mounted on an enclosure and an electronic protection device located within the enclosure facilitates alignment between the coupler and the electronic protection device during installation and requires no tool for installation. The coupler is positioned over an opening in the electronic protection device and oriented such that a first coupling portion is configured to engage a complementary coupling portion on the electronic protection device. The coupler may be manually mounted, engaging the complementary coupling portions on the door handle coupler and the electronic protection device without requiring a tool for installation. The coupler includes an upper sleeve configured to receive an axle, also connected to the activator, that rotates independently of a lower sleeve which is mounted to the electronic protection device, facilitating orientation of the activator on the outside of the enclosure. The coupler also provides for local lock-out of the electronic protection device.

Switch gear for interconnecting a plurality of power transmission lines including a number of high voltage switches arranged in three phase unitized relationship for routing power. The switches are each pre-mounted on a transverse beam which is operatively attached between two oppositely disposed longitudinal parallel beams forming a unitized switch assembly with a common base structure with a transformable parallelogram outer perimeter which may be attached in the field to a support structure. The outer perimeter of the common base structure of the unitized assembly transformable common base can be transformed with a power actuator from a rectangular configuration to a rhomboid configuration that permits the width of the unitized assembly to be reduced so that the assembly can be transported by truck to an installation site and then the switch assembly may be transformed back to the rectangular configuration with the final width for installation at the site.

A lever switch device includes a shaft member, a rotary operation member, a push switch, and a flexible board. The flexible board has a first board part, a first wiring part connected to the first board part, a second board part, a second wiring part connected to the second board part, and an integrated wiring part. The first board part has a fixed contact. A movable contact of the rotary operation member comes into contact with and separates from the fixed contact in response to a positional shift of the rotary operation member. The second board part receives a signal output from the push switch. The integrated wiring part is at a position away from the first board part and the second board part, and a part of the first wiring part and a part of the second wiring part are integrated in the integrated wiring part.

A switch control device includes a casing, a motor, a control unit, and a push arm. The casing includes a mounting wall adapted to be mounted on a mounting surface, and a surrounding wall extending transversely from the mounting wall. The motor is disposed in the casing and has a rotary shaft extending through the surrounding wall. The control unit is connected to the motor. The push arm is disposed outside of the surrounding wall and is coupled to the rotary shaft so as to be driven to rotate relative to the casing without touching the casing, between a pushing state and a release state, thereby controlling the switch.

The Ohmni-Switch is a system that enables a person to use an existing wall switch/receptacle circuit to control outlets that are not wired in that existing wall switch/receptacle circuit. The transmitter and receiver circuits will be housed in a sealed plastic case. All external surfaces of the devices will not have any contact with the house 120 VAC mains.

Systems and methods provide an electrical bus plug on a busway, where the electrical bus plug is universal and configured to fit a plurality of busways. An adapter may fit on the electrical bus plug to allow the bus to properly electrically connect with the specific type of busway. Optional mounting brackets can also be removably attached to the universal electrical bus plug to permit attachment to a specific type of busway. Therefore, a single/universal electrical bus plug can be used to electrically connect to a plurality of busway types through the use of an adapter and mounting hardware that attached to the universal bus plug.
