A limit switch includes a housing, a plunger, an actuator, a prime contactor, a redundant prime contactor, an adjustment contactor, and a redundant adjustment contactor disposed within the housing. The prime contactor and adjustment contactor are electrically coupled in series. The prime and redundant prime contactors are openable by the plunger, and the adjustment and redundant adjustment contactors are closable by the plunger. The redundant adjustment contact is electrically coupled in series with the redundant prime contactor. The limit switch controls a circuit by aligning the limit switch in a mid-position alignment. Opening the prime contactor or redundant prime contactor de-energizes the electrical circuit. Closing the prime contactor and the redundant prime contactor while the adjustment contactor and the redundant adjustment contactor are maintained closed energizes the electrical circuit. Opening the adjustment contactor or redundant adjustment contactor when the actuator is misaligned from the plunger de-energizes the electrical circuit.
