なる優れた効果がある。As described above, in the present invention, when an emergency detection signal is generated from an electronic device, the power supply to the electronic device is cut off by switching the path by the two-path switching relay, and the first shutoff is performed by the power supply and alarm. Since the alarm is generated by forming a circuit, it can be configured as a two-path switching relay with only one common movable contact, making it simple and compact.Moreover, the relay coil can also be used with a small current capacity, making it suitable for electronic equipment. It is possible to cut off the power supply to the electronic device to make it safe, and also to issue an alarm with a simple configuration using a two-path switching relay. When detected, the power supply and the alarm form a second closed circuit independently of the power supply circuit to the electronic device and issue an alarm. When an emergency situation occurs, it is possible to issue the same alarm as the electronic equipment when an emergency situation occurs without interfering with the control operation of the electronic equipment, which is an excellent and practically useful effect.
