A method and apparatus utilizing a low voltage level actuator and a signal processing device such as a microprocessor to selectively electrically couple an electrical appliance with a switch circuit associated with a power source of relatively high voltage. The microprocessor is responsive to low level electrical signals from the actuator to control operation of the switch circuit and the appliance without posing a shock hazard to the user. One form of actuator includes a piezoelectric element.
