ABSTRACT:
A user, touch actuable capacitive switch for changing the level of an output signal to an electrical circuit. The switch includes an external, user touchable capacitive plate formed on a first dielectric panel and two internal capacitive plates formed on a second dielectric panel affixed to the first flexible dielectric panel, the two internal capacitive plates being oppositely disposed from said external capacitive plate on opposite sides of said second dielectric panel. Electrically conductive paths on the second dielectric panel interconnect the internal capacitive plates to the electrical circuit. A trim tab formed on the second dielectric panel permits the adjustment of the change of level of the output signal upon actuation of the capacitive switch.
