Abstract
A circuit board has a socket opening for a twist-in lamp bordered by a pair of arcuate conductors. The circuit board is configured to define a socket for a bi-pin lamp located concentrically within the opening and supported by bridges across the opening. The bridges carry conductors for the bi-pin lamp. The bridges are frangible to allow the socket for the bi-pin lamp to be removed. When a bi-pin lamp fails in service it is removed along with its socket and a twist-in lamp is installed in the remaining socket.
Claims8
A combination lamp receptacle which permits initial installation of a first type of lamp and replacement by another type of lamp in a circuit board comprising:
- a first receptacle concentrically positioned within a second receptacle so that the first receptacle interferes with the second receptacle until the first receptacle is removed;
- the first receptacle being supported within the second receptacle by circuit board bridge means, the bridge means being subject to breaking for removal of the first receptacle;
- each receptacle having conductive contacts coupled to conductors on the circuit board.
