PROBLEM TO BE SOLVED: To provide a switch that copes with security measures for an automatic machine facility such as a machine tool. SOLUTION: The thermosensitive switch is composed of a thermosensitive section (20) that provides an output of an electric signal with a quantity in response to a heating value of an object to be sensed which the thermosensitive switch approaches or with which the thermosensitive switch is in contact, a sensing section (30) that compares the quantity of the electric signal from the thermosensitive section (20) with a reference signal to produce a sensing signal when the quantity of the electric signal exceeds the reference signal, and an output section (40) that outputs a switch ON signal at the reception of the sensing signal from the sensing section.
