とする切替制御回路。[Claims for Utility Model Registration] Switching that controls the operation status of two communication channels connected to the contacts of two relays having the same characteristics to be switched based on the connection/disconnection between the contacts of the relays and the ground air. In the control circuit, one ends of the coils of the two relays are connected to the contacts of the other relays, and the two relays are connected to each other.
A coil drive voltage is applied to the other ends of the coils of each of the two relays, and the coil currents of the two relays mutually flow depending on the contact states of the other relays and the coil drive voltage, thereby forming the communication path. A switching control circuit comprising means for controlling switching.
