ABSTRACT:
A snap acting thermostat is described which is suitable for miniature construction and utilizes a thermostatic snap acting disc, one edge of which actuates the contacts. The force of the thermostatic disc forces the contacts closed in one temperature condition by acting on the contact end of the contact strip, the entire length of which is resilient. This permits sufficient movement of the contacts for usable voltage and current ratings without excessive metal fatigue in the physically short contact strip.
