Abstract

A common ground terminal is adapted for use with wedgebase lamp bulbs of either the single filament of dual filament type in a single filament lamp socket. The common ground terminal has a pair of opposed, upper and lower spring contact arms which biasingly engage opposite sides of a wedgebase when it is inserted into the space between the spring contact arms. The lower spring contact arm has a second spring tab which accommodates the presence of a second contact wire when the dual filament type of wedgebase lamp bulb is used.
