The present invention relates generally to a universal programmable voltage module that activates and deactivates an electrical component based on a programmed voltage or voltage change on a multiplexed input. The universal programmable voltage module may have input circuitry for conditioning the multiplex input for a processor configured to execute instructions from a computer-readable medium; at least one control switch; power conditioning circuitry receiving power from a battery; at least one visual indicator; and switched output circuitry. Methods of operating the universal voltage module in both a momentary and a latched mode are also provided.
