Abstract
A programmer/timer for an appliance of the type having a rotatable program cam advanced by an oscillating pawl engaging a ratchet wheel for actuating at least one appliance function switch. A shaft is provided for enabling user positioning of the cam after limited rotational lost-motion for selecting the program interval. An annular member having a conical cam surface is received over the shaft and is helically cammed to the shaft. During the limited lost-motion rotation of the shaft, the collar moves axially and the conical cam surface lifts the pawl from the ratchet thereafter enabling user rotation of the program cam for positioning same for program interval selection.
