The Remote Controlled Switch are ideal for the remote operation of many electrical devices, including lamps, appliances,This circuit provides power control without running line-voltage switch leads. The primary of a 6-volt filament transformer is connected between the gate and one of the main terminals of a triac. The secondary is connected to the remote switch through ordinary low-voltage line. With switch open, transformer blocks gate current, prevents the triac from firing and applying power to the equipment.Closingthe switch short-circuits the secondary, causing the transformer to saturate and trigger the triac.
