Abstract: Systems and methods are disclosed herein relating to a momentary contact switch that can be both manually and electronically actuated. In some embodiments, an electronic module can be added to a manual momentary contact switch to enable electronic control. The momentary contact switch can be transitioned between first, second, and third electrical states based on the rotation of a shaft between first, second, and third rotational positions. Rotary arms are selectively engaged by pull arms connected to a master solenoid to selectively rotate the shaft from the first rotational position to the second and third rotational positions.

Abstract: A circuit breaker includes a trip mechanism having reduced trip movement and an integrated signal flag. The trip mechanism includes a spring-biased trip lever and a latching member for keeping the trip lever in an on or latched position. Upon occurrence of an abnormal current condition, the latching member is moved away from the trip lever to trip the trip mechanism. The latching member also has a catch mechanism designed to catch the trip lever after it is released, thereby halting further progress of both the trip lever and the latching member. As a result, less space is needed within the circuit breaker for trip movement compared to existing solutions. Moreover, the location of the catch mechanism on the latching member is selected such that the halting of the latching member places the integrated signal flag in an optimal viewing position within a viewing window.

Abstract: An EVCS equipped with an accelerometer to detect seismic events. Upon sensing a catastrophic environmental event, the EVCS is automatically disconnected from the main utility power source. A controller powered by a backup or alternate power source inside the EVCS monitors the seismic activity, and upon sensing the seismic event is over, the EVCS automatically performs a startup check. If utility power is present and the self-check passes, the EVCS resets and provides power from the main utility to the charging connector. If the EVCS is operable but utility power is unavailable, the EVCS switches to a generator or a UPS. The EVCS can provide multiple power outlets, including USB outlets, and emergency lighting. The EVCS can also be retrofitted or constructed with a communications interface for communicating status and operational information following a seismic event.
