ABSTRACT:
A resettable, current-responsive, circuit interrupter device is made by blanking two wide but thin terminals and carrier stubs therefore, and embedding them up to a substantial part of their thickness in a side wall of an insulating housing so that sides of the embedded terminal portions are exposed from the housing material along the side wall inside the housing, so that terminal ends extend from the bottom of the housing to be connected in a circuit and through the top of the housing to be accessible for test purposes. An electrical contact is secured on an exposed side surface of one embedded terminal portion and a thermostatic strip element is secured to an exposed side surface of the other embedded terminal portion to extend closely along the one housing side to normally engage the contact in a very compact, closed circuit position of the device. The thermostatic strip element has a selected resistivity and the wide terminals have substantial current capacity so the thermostatic strip self-heats to a selected temperature to open the circuit in response to occurrence of a precisely predetermined overload current condition in the device circuit at any ambient temperature likely to be encountered in an automotive environment. The corner portions are then blanked from the terminals. A lid is disposed to overlie the thermostatic strip element.
