Claims

[Scope of utility model registration request]

It is used by being placed over a relay consisting of a bimetal and a heater for operating it housed in a case with at least two terminals protruding from the top surface. a case having a relay storage section in which the relay can be stored in the thermistor storage section; a positive temperature coefficient thermistor having electrodes on both main surfaces and housed in the positive temperature coefficient thermistor housing section; and one of the positive temperature coefficient thermistors. The first terminal is connected to the electrode of the positive temperature coefficient thermistor and has one end pulled out outside the case, and the other terminal is connected to the other electrode of the positive temperature coefficient thermistor and has one end pulled out outside the case. a second terminal having an end located within the relay housing at a position corresponding to one terminal of the relay and having a structure to fit with the terminal; and a second terminal having one end pulled out outside the case. A third terminal, the other end of which is located within the relay housing and corresponds to the other terminal of the relay, and is structured to fit with the other terminal.
