Abstract
A drive mechanism for a program timer of the type having a rotating member advanced in a step-by-step manner by a drive pawl includes a drive cam having a camming surface defining the drive stroke of the drive pawl. In order to shorten the switching time, the drive cam is intermittently rotated by an angle sufficient to drive the pawl to advance the rotating member during a single intermittent movement of the drive cam. Sub-interval switching is accomplished by the cooperation between a pivotable sub-interval switching lever and a sub-interval camming surface on the drive cam, with the lever actuated by the camming surface to control the movement of a sub-interval switch blade.
