Abstract
A thermostat employing a lever for selecting the temperature setting has a detent mechanism for creating individual detent positions associated with temperature setting values. In a preferred embodiment the detent mechanism comprises ridges and valleys in the surface of the baseplate on which the thermostat elements are mounted. A projection on the setting lever engages the individual valleys to create the detent effect, and a edge of the cover cooperates with resiliency of the lever to deflect the lever so as to cause the projection on the lever to continually engage the ridges and valleys. Another embodiment has ridges and valleys on the edge of the cover which engage a first projection on the lever. A second projection slides along the baseplate surface and cooperates with resiliency of the lever to deflect the lever creating force urging the first projection into continual engagement with the ridges and valleys.
