LAMPHOLDER HAVING TERMINALS OF THE INSULATION-DISPLAYING TYPE ABSTRACT OF THE DISCLOSURE A lampholder, of the type intended to support and supply electrical current to an incandescent lamp bulb, has terminals movable from normally retracted positions to positions in which they displace the insulation sheath of a current-supplying conductor wire, so as to make elec- trical contact with the conductive element of the wire. On movement of the insulation-displaying terminals to positions in which they displace the wire insulation and make contact with the wire conductors, the terminals are latched automatically against retrograde movement. Means is provided for facilitating the wiring of the lampholder to supply current either to single-filament or two-fila- ment lamps, whether in association with a single lamp of the single-filament or double filament type, or alterna- tively in parallel with one or more additional single or double filament lamps. The lampholder can if desired be made as an interior for use in shells already standard in the industry, and in addition, is adapted to be made either with switches (for example, rotary turn knob switches) or alternatively, as a keyless device.
