Abstract

PURPOSE:To conduct remote ON-OFF operation without breaking an input power source and simplify constitution by a method wherein a photocoupler is utilized. CONSTITUTION:When a remote ON-OFF switch S is turned OFF, a drive transistor Q2 is turned ON, and a capacitor C1 is charged. When the charging voltage reaches some value, a trnaistor Q1 is turned ON, and the transistor Q2 is turned OFF. When the exciting energy of a drive transformer T1 is fed back to an input power source V1 from feedback winding N5 and the feedback is completed, the transistor Q2 is turned ON, and switching operation is thereafter conducted by repeating this cycle. When the remote ON-OFF switch S is turned ON, a light-emitting diode CR11 radiates, a phototransistor Q5 is turned ON, and the transistor Q2 is kept at OFF.
