PUSH BUTTON SWITCH WITH SPIRAL ABSTRACT OF THE INVENTION The conventional push button switch which is generally found on lamps and appliances is constructed so that depressing the push-button causes a rotary switch motion within the body or the switch. The components which convert the linear motion of the push-button have consisted of a metal spiral stem and a cooperating metal pushbutton. In addition the spiral stem has been provided with a washer at its lower extremity. The present invention provides for the spiral stem and washer to be molded as a single plastic component. The cooperating push button is provided as a plastic component or as a metal component with a plastic insert. The improvement described serves to reduce the number of component parts in a pushbutton switch as well as isolating the operator of the push button from the internal electrical components.
