Thermal protector

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 the rear end portion of said movable plate, the rear end portion of said bimetal plate, and one end portion of said second terminal for external connection are superposed on each other and supported, and said movable plate and said second terminal for external connection are electrically connected to each other in a position close to said movable contact in the superposed support portion to substantially decrease the internal resistance.
