Relay equipped with auxiliary module

The invention discloses a relay equipped with an auxiliary module. The relay comprises a relay body and the auxiliary module mounted on one side of the relay body; the auxiliary module comprises a first contact structure, a second contact structure and a third contact structure; the auxiliary module also comprises a transmission mechanism connected with an electromagnetic driving mechanism and the third contact mechanism to drive the third contact structure and the electromagnetic driving mechanism to act synchronously; and when the electromagnetic driving mechanism releases or attracts actions, the third contact structure is driven by the transmission mechanism to be in contact with the first contact structure or the second contact structure in a matching manner. By virtue of the technical scheme, the working state of the relay can be known conveniently through the auxiliary module, so that the relay is convenient to use; in case that the relay suffers from a fault, information feedback can be obtained in ti
