Relay check -up seat

The utility model provides a relay check -up seat, including relay base, switch, additional equipment terminal, feedback terminal, pilot lamp A, pilot lamp B and battery, the coil contact of relay base passes through the wire and connects additional equipment terminal constitution coil power return circuit, each normally open contact of relay base passes through the wire and establishes ties in proper order and connect feedback terminal component feedback loop, each normally open contact of relay base passes through the wire and establishes ties in proper order and connect pilot lamp A component normally open contact detection circuitry, and each normally closed contact passes through the wire and connects in parallel in proper order and connect pilot lamp A component normally closed contact detection circuitry, and normally open contact detection circuitry connects with normally closed contact detection circuitry and through wire and battery and normally open contact 0 component contact work instruction return circuit, this relay check -up seat simple structure, small, easy and simple to handle high efficiency, safe and reliable are applicable to multiple model relay to can reflect normally open contact and the normally closed contact action condition in the checking procedure.
