Abstract
An illuminated electrical push button switch has a pair of spring contacts secured in a housing on either side of a miniature bulb. The contacts have inclined bifurcated ends that bear resiliently against the underside of the push button. Depressing the button causes the bifurcated contact ends to deform elastically and come together making electrical contact. The pigtail leads for the bulb are sandwiched between the contacts and a block portion of the housing, all being held in place by a screw that also functions as a binding post for the external wire connection.
