REMOTE_ON_OFF_SWITCH

Published:2009/6/29 3:47:00 Author:May | From:SeekIC

This circuit provides power control with-out running line-voltage switch leads. The primary of a 6-volt filament transformer is con-nected 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 switchshort-circuits the secondary, causing the transformer to saturate and trigger the triac.
