ABSTRACT:
a temperature switch is disclosed which has a bimetal disc being inversely deformed between a concave shape and a convex shape according to a temperature change. A bottom portion including the outer periphery of a casing of the temperature switch is in a plane shape. At an inner position of the outer periphery of the bottom portion, a protruding line for supporting an outer peripheral portion of the disc is formed. When the temperature switch is used in such a way that the outer surface of the bottom portion is in contact with a test subject, since heat is transferred from both iner and outer side walls of the protruding line to the disc, the delay of thermal transfer can be reduced.
