Abstract
A multiple bimetallic snap disc thermostat is disclosed in which two series connected switch mechanisms are respectively operated by two concentric bimetal snap discs having the same diameter. One snap disc is thermally automatic in operation to open and close its associated switch upon reaching its calibration temperatures. The outer disc is a one-shot disc which does not automatically reset and cannot be manually reset after operation. The two discs are mounted in a single, disc retaining cup, and are spaced by a ring positioned between their peripheries. This allows said discs to be formed of the same size and provides easy mounting. A single fixed contact member provides the fixed contact for both switches. The contacts of the switch associated with the automatic disc are capable of repeated operation whereas the contacts of the switch associated with the one-shot disc are not structured for repeated cycling.
