Abstract

PURPOSE:To ensure proper operation even if there is a trouble in one of contact points by connecting a plurality of parallel circuits in series comprising a plurality of parallel contact points, and making said connection group a single equivalent contact point. CONSTITUTION:When a switch SW closes, electric current flows to a circuit comprising a battery Ba, the switch SW, an exciting coil L and a current limiting resistor R, thereby causing the operation of a relay Ry and closing all contacts S1 to S4 thereof. Consequently, a conductive state is generated between terminals T1 and T2. When the switch SW opens in this state, current to the exciting coil L is interrupted and the contact points S1 to S4 all open to restore the original state thereof, thereby generating a non-conductive state between the terminals T1 and T2. According to the aforesaid system, even if any of the relay contact points S1 to S4 is out of order, the relay can give proper operation virtually.
