Abstract

PURPOSE: To miniaturize a relay with the current capacity of the relay contact reduced, by connecting a switch element such as a SCR in parallel to the relay contact and by making a rush current with a large load bypass by the switch element.
CONSTITUTION: Voltage-inducing coil 2, coupled magnetically with contact-driving exciting coil 1, is connected to the gate of switch element 3 such as a SCR connected in parallel to normally-opened relay contact 4, and by its output voltage, switch 3 is ignited to conduct. Switch 3 conducts to flow the current of load 5 to switch 3, and then, realy 4 is closed to flow the load current to the relay contact as well. Namely, since the rush current of load 5 flows to switch 3, the current capacity of the relay contact can be reduced and fusion-welding resistance can be also improved
