PROBLEM TO BE SOLVED: To provide a low-cost, irreversible temperature-sensing switch, that is installed in various portions of various machines and equipment, can detect abnormalities and troubles of the operation of the machines and equipment due to the temperature increase of the relevant portion, has sure operation, and has no possibility of failures. SOLUTION: In a case body, between a pair of electrode plates energized in the direction which come into contact with each other, an electrically insulating wax layer that begins to melt at an arbitrary set temperature is sandwiched in-between.
