Abstract:
1. A retainer system usable in combination with a positive temperature coefficient resistor in a housing shaft having a shaft side wall, the retainer system being of a type suitable to be secured within the shaft with a spring portion of the retainer system flexed to a desired extent and with a contact surface of the retainer system being urged against the resistor to retain the resistor in the shaft, the retainer system comprising: a) a base having a longitudinal axis, b) a spring, wherein the spring has a portion extending radially outwardly from the longitudinal axis of the base and has a neck adjacent a radially outward portion of the radially outwardly extending portion of the spring that curves radially backwardly toward the longitudinal axis, the spring also comprising a contact extending from the neck radially inwardly to the longitudinal axis, the contact having a contact surface presented outwardly, away from the base and extending to the longitudinal axis, and c) a plurality of shaft engaging members for engaging the shaft side wall and securing the base within the shaft at a desired distance from the resistor; wherein the spring extends from an outer perimeter of the base.
