The wedge-shaped arms having a flat surface and a sloped surface formed at an angle with respect to the flat surface and converging in a direction of the flat surface. A housing base is constructed and arranged to slidably receive the cam member. A support member is connected to the base and has spaced apart electrical contacts and an electrical circuit associated therewith. A non-metallic, flexible dome is carried by said support member, and an electrically conductive element is positioned on the underside of the dome for engagement with the spaced apart contacts and closing said circuit when said dome is collapsed.
