。[Scope of Claim for Utility Model Registration] A detection switch that is connected to a master station that performs transmission and reception via a transmission line and has a transmission function that can send the on/off status of the contact back to the master station, integrated within the case. The transmission circuit section includes a detection circuit and a counter circuit for detecting a transmission signal from the master station, and a detection circuit and a counter circuit for detecting the transmission signal from the master station, and receives the transmission signal from the master station to obtain operating power. When the count value by the counter circuit matches a preset value, it passes or shorts the transmission signal according to the on/off state of the internal switch and returns it to the master station. A detection switch equipped with a transmission function characterized by:
