Abstract
A thermal protector includes a metal housing having open and closed ends, a header plate secured to the housing so as to close its open end and having two through-apertures, first and second terminal pins hermetically secured in the respective apertures of the header plate so as to extend into the housing, a dish-shaped bimetal disposed on an inner bottom of the housing so that one of its two sides is in contact with the inner bottom face of the housing, an elastic support disposed in the housing to be opposite to the other side of the bimetal for supporting it, a pair of fixed and movable contact members welded to the first and second terminal pins respectively such that a straight line passing through the center of the first terminal pin and a location of the fixed contact member welded to the first terminal pin is approximately parallel to a straight line passing through the center of the second terminal pin and a location of the movable contact member welded to the second terminal pin and vice versa and further such that the location of the fixed contact member welded to the first terminal pin is not substantially opposed to the location of the movable contact member welded to the second terminal pin and vice versa, and a pressure strip disposed between the support and the movable contact member for transmitting movement of the support due to reversion of the bimetal to the movable contact member.
