Abstract
An electrical switch comprises first and second switch elements including respective first and second electrically conductive flexible domes for selectively making electrical connections. The second switch element is disposed adjacent the first switch element with an electrical conductor therebetween. An actuator is movable for exerting force on the second switch element via a spring, and for exerting force on the first switch element via the spring and the second switch element. The second flexible dome may have an actuating force that is less than the actuating force of said first flexible dome.
