An electrical noise reduction circuit which includes field-effect transistors and a photocoupler, for use in alternating current circuits in conjunction with an electro-mechanical relay. The circuit essentially reduces the function of the electro-mechanical relay to that of a safety block, the function of contact closing being taken over by the time-delayed semiconductor devices of the noise reduction circuit.
