Abstract: The present invention is a remotely actuated emergency stop (E-stop) switch, with equipment control circuitry, providing a method for testing the E-stop switch and control circuitry to assure circuit and switch integrity, anytime, without equipment operational interruption, and without negating the manual actuation function of the E-stop switch to immediately cut all power to the equipment. The E-stop switch includes a first relay governing a first control circuit and a second relay governing a second control circuit. Each control circuit governs a motor source control contactor, which, when closed, provides power to the equipment. Transferring energization, and motor control, from the first control circuit to the second control circuit, and vice-versa, allows testing, in turn, of the de-energized components of the E-stop switch and control circuitry while the equipment remains operational. Remote actuation and circuit monitoring and testing is controlled by a Program Logic Controller (PLC).
