ABSTRACT:
A microprocessor controlled appliance is provided which has a smooth unbroken control surface. A control panel assembly includes a support panel and a decorative panel overlying the support panel. The assembly further includes a continuous flexible membrane layer. The support and decorative panels each include a generally aligned opening providing rear communication with the flexible membrane layer. A power source provides power between a pair of electrical conductors for energizing the appliance. A manually-set electrically-reset switch is associated with one of the conductors and is mounted to the support panel below the flexible membrane layer. The switch is manually operable to a closed position by depressing the membrane layer through the opening to complete a circuit across the pair of conductors for powering-up the microprocessor controlled appliance. Mechanism is provided for holding the switch in the closed position including a portion engageable with the switch. A device is operable responsive to the microprocessor for effecting disengagement of the mechanism to effect resetting of the switch to its normally open position.
