ABSTRACT:
An appliance timer incremental drive is provided with an electronic circuit that generates a nonvarying camstack motor advancement pulse that cooperates with a cam-operated motor control switch. When the motor control switch is closed, a power circuit is completed with a camstack drive motor and the camstack rotates. When the motor control switch opens, the power circuit is also open, so the camstack is stationary. The camstack remains stationary, delayed, until the electronic circuit, which operates independently from the camstack, provides a nonvarying camstack advancement pulse to power the camstack drive motor to rotate the camstack.
