A switch for an electrical circuit including a base, a cam rotatably coupled to the base and defining a first profile and a second profile, a solenoid having alternating first and second cycles, a link including a first portion and a second portion, and a member configured to move between an extended position and a retracted position and comprising a cam follower configured to follow the second profile. The first profile of the cam includes a first position, a second position, a third position, and a fourth position. The first cycle of the solenoid includes a first energized state and a first de-energized state and the second cycle of the solenoid includes a second energized state and a second de-energized state. |
