Electrical switching device
Abstract:
An electrical switching device facilitates selectively controlling residential power. The switching device is configured to couple between a residential electrical-energy meter and a residence. The device includes a solenoid assembly, a yoke, and at least two conductor busbars. The solenoid assembly includes an electrically-activated solenoid that is coupled to an actuator assembly. The actuator assembly includes a biasing mechanism and a plunger. The yoke is coupled to the actuator plunger such that the plunger is substantially centered relative to the yoke. The biasing mechanism is coupled to the yoke to bias the yoke away from the solenoid. The yoke includes at least two shorting bars that are oriented in a mirrored-arrangement on opposite sides of the actuator plunger. The solenoid assembly selectively moves the yoke between a first position in which the shorting bars are spaced a distance away from the conductor busbars, and a second position in which each of the shorting bars are electrically coupled against the conductor busbars. Each of the at least two conductor busbars has a substantially rectangular-shaped cross-sectional profile.
