A switch for an electrical circuit includes a base, a rotatable cam having a first profile and a second profile, a solenoid, a link, and a member comprising a cam follower configured to follow the second profile. A 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. A first portion of the link couples to the solenoid, and a second portion of the link movably couples to the first profile of the cam. When the solenoid is in a first cycle, the member moves from a retracted position to an extended position, and when the solenoid is in a second cycle, the member moves from the extended position to the retracted position. |

1. A switch for an electrical circuit, comprising:
a base; a cam rotatably coupled to the base and defining a first profile and a second profile, the first profile including a first position, a second position, a third position, and a fourth position; a solenoid comprising alternating first and second cycles, the first cycle including a first energized state and a first de-energized state and the second cycle including a second energized state and a second de-energized state; a link including a first portion and a second portion, the first portion coupled to the solenoid, the second portion movably coupled to the first profile of the cam; 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; wherein when the solenoid is in the first cycle, the member moves from the retracted position to the extended position, and wherein when the solenoid is in the second cycle, the member moves from the extend position to the retracted position. |
