A program timer for use with commercial or consumer appliances provides a single user knob interface that allows the desired selection of a programmed cycle and a push-to-start function. To preclude inadvertent program operation and enhance the life of the program timer, a snap-action switch is utilized to provide the push-to-start functionality. As such, actuation of the start switch provides a positional hysteresis that prevents teasing of the switch. The rapid snap-action opening and closing of the switch contacts precludes or minimizes the arc sustained between the contacts so as to greatly increase the life of the start switch. In one embodiment an actuation wheel larger in diameter than the program cam stack of the timer is utilized to pivot a lever to actuate the snap-action switch.
