BASE FOR A THREE-WAY LAMP Abstract of the Disclosure A modified lamp includes first and second filaments contained in an envelope to which power is selectively provided individually or conjunctively to obtain three distinct light levels. A contact member in the lamp base is modified to include a planar surface over a major portion of its radial width. Additionally, a lead wire opening that receives one of the lead wires extending from one of the filaments, is spaced from the planar surface to limit the potential for electrical contact with a tang of an associated socket. In one preferred embodiment, the lead wire opening is disposed in a recess that has a maximum circumferential dimension less than the cross-section of the tang to preclude advancement of the tang into the recess. A flat is provided along the outer periphery of the contact member to provide accurate orientation of the contact member during lamp assembly.
