ABSTRACT:
A secondary timer mechanism for controlling a secondary program function independently of a first program function. A main timer mechanism controls the first program function and is operatively driven by a motor. A second timer mechanism can be set independently of the main timer mechanism and engages the motor through a drive gear in a first axial position and is in non-engaging relation with the drive gear in a second axial position. The second timer mechanism includes a peripheral cam surface that cooperates with a cam follower to advantageously control selective electrical connection between contact portions. The contact portions regulate the secondary program function. Pins are operatively included in the second timer mechanism for maintaining an engaged relationship with the drive gear.
