ABSTRACT:
A PTC starter that is electrically connected to an asynchronous motor by pins that extend through holes into the starter housing, which includes an open top, generally box shaped base portion and a cover having a downwardly opening recess mountable on the base portion. Support structure is provided in the base portion for loosely retaining a disc shaped PTC resistor and a pair of contact members on opposite sides of the resistor in a loose stacked relationship with the resistor, the support structure including a base portion receptacle for loosely retaining an electrical terminal bushing portion adjacent to a contact member. The cover in having its recessed portion moved downwardly along the contact members and resistor result in the contact members being resilient retained in electrical engagement with the resistor electrode surfaces, and at least two terminals extending upwardly through the cover. Advantageously the housing mounts a thermal protective switch for the motor.
