ABSTRACT:
A lampholder with means for circuit interruption upon lamp removal is provided with a pair of circuit interrupting contact members that are located within a housing by means of projections from the housing front and back elements. One of the contact members has a pin contacting portion substantially perpendicular with the housing front wall and having a pair of pin locating projections thereon. Insertion of a lamp causes the first contact member to be forced outwardly to contact the second contact member in a manner that results in a contact wiping action therebetween. The contact means for the other lamp pin is preferably of the type having a pin contacting portion that is flat and parallel with the housing front wall.
