ABSTRACT:
An adjustable thermostat is disclosed which has an operating temperature range and in which detent means is provided to establish a plurality of detent positions of a rotatably adjustable shaft for selected operating temperatures of the thermostat. The detent means includes a radially extending, arcuate flange rotatable with the shaft and cooperating with a post on the base. The flange has a plurality of radial notches to establish the plural detent positions in engagement with a projection on the post. The flange is integral with an arcuately extending wall, the wall having inner and outer arcuate surfaces, and the entire wall is deformed and stressed by radial camming action as the shaft is moved from one detent position to another. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
