Abstract:
1. An electrical switch comprising: a base having at least first, second and third electrical conductors thereon; a housing cover disposed adjacent said base, said housing cover having walls defining a central cavity, and having an opening therethrough; an electrically conductive flexible dome disposed in the cavity of said housing cover, said flexible dome having a plurality of relatively longer legs extending from a dome portion thereof and being in electrical contact with the first electrical conductor of said base, said flexible dome having a relatively shorter leg extending from the dome portion thereof and overlying the second electrical conductor of said base, and the dome portion of said flexible dome overlying the third electrical conductor of said base, said flexible dome having an actuation distance, wherein the relatively shorter leg of said flexible dome comes into electrical contact with the second electrical conductor when said flexible dome is pressed with a first actuation force, and wherein the dome portion of said flexible dome comes into electrical contact with the third electrical conductor when said flexible dome is pressed with a second actuation force; a pushbutton disposed in the opening of said housing cover, wherein said pushbutton is movable in the opening of said housing cover for exerting force on said flexible dome; and at least one spring extending from said base for providing an electrical connection to at least one of the first, second and third electrical conductors of said base.
