Patent ID: 7126068

Claim:
A switching mechanism comprising: a first actuator plate to operate a first circuit breaker connected to a primary power supply, the first actuator plate movable between on and off positions; a second actuator plate to operate a second circuit breaker connected to a secondary power supply, the second actuator plate movable independently of the first actuator plate between on and off positions; an actuator movable between first and second positions, the actuator being operatively connected to the first and second actuator plates in a manner to: move the first actuator plate to an on position and the second actuator plate to an off position when the actuator is moved to the first position; move the first actuator plate to an off position and the second actuator plate to an on position when the actuator is moved to the second position; enable movement of one of the first and second actuator plates between the on position and the off position when the other actuator plate is in the off position.
