Abstract:
A thermal protector comprising:a fixed plate provided with a fixed contact in the front end portion and a first terminal for external connection in the rear end portion; a movable plate having elasticity so,that a movable contact provided in the front end portion thereof is brought into contact with said fixed contact by the elasticity; a second terminal for external connection connected to the rear end portion of said movable plate; and a bimetal plate, the front end portion thereof being engaged with said movable plate, for driving said movable plate in a direction such that said movable contact is separated from said fixed contact by reversing when a predetermined temperature is exceeded, wherein a part of said movable plate has a double construction provided by folding, and an increase in cross-sectional area due to said double construction substantially decreases the internal resistance.
