Abstract

A machine controller having start and time delay functions activated and set by a single switch. There is a cycler for activating and deactivating machine functions in a timed sequence. There is a manually operable start/delay-set switch and an electronic circuit responsive to the switch which produces a start signal upon initial closing of the switch, and which produces a delay signal after the switch is held closed for a predetermined time. An electronic control circuit responds to the start and delay signals to store a delay time and activate the cycler after the stored delay time has expired.
