ABSTRACT:
A contact arrangement for a tubular lamp which is arranged in a housing and is provided at each end with a spherical or cylindrical lamp terminal. A contact piece having a substantially semicylindrical recess is arranged in the housing for receiving the lamp contact terminal. A pressure plate is movably connected at one end thereof to a support block. A further end of the pressure plate rests upon the lamp contact terminal. The housing is provided with a cover which contains a resilient spring. When the housing cover is in place, the resilient spring exerts a force upon the pressure plate which holds the lamp contact terminal in place within the recess of the contact piece. In this manner, the lamp can be removed and replaced without exerting mechanical stress in the axial or radial directions.
