THERMOSTAT HAVING A TEMPERATURE SETTING LEVER WITH TACTILEY DETERMINABLE POSITION

摘要

A thermostat employing a lever for selecting the temperature setting has a deten t mechanism for creating individual detent positions associated with temperature s etting values. In a preferred embodiment the detent mechanism comprises ridges and vall eys 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 det ent effect, and a edge of the cover cooperates with resiliency of the lever to deflect the l ever so as to cause the projection on the lever to continually engage the ridges and valley s. 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 su rface and cooperates with resiliency of the lever to deflect the lever creating force urgi ng the first projection into continual engagement with the ridges and valleys.
