Abstract

PURPOSE:To provide possibility of initialization when power is turned off, by closing a relay contact when the power is off, and allowing the discharge current in a capacitor to flow to a latch type relay reset winding. CONSTITUTION:When power is connected and turned on between a power terminal 11 and a terrestrial air terminal 12, a current flows in a relay winding 13, and the movable contact 15b of relay contact 15 is opened, and at the same time, a capacitor 16 is charged with DC. When the power is put off, no current flows in the relay winding 13, and the movable contact 15b of the relay contact 15 is closed, and discharge current flows this capacitor to reset windings 17-19 of a latch type relay, which is thus reset. Therein a diode 14 prevents the discharge current of the capacitor 16 from flowing to the power terminal 11 side. This enables initialization when power is turned off.
