Radiant fusers utilizing quartz lamps typically require precise location of the lamp filament to maintain focus of the radiant energy on the toner to be fused. This is normally accomplished by precise location of the electrical socket in which the lamp is mounted. Typically, in such situations removal of the lamp may require removal of the contact with the accompanying disturbance of its location adjust-ment. The figure illustrates a wire-form lamp socket electrical contact 10 which utilizes a torsion spring thereby allowing removal of the lamp from the fuser without disturbing the location settings. Thus, in the figure the torsion spring wire-form lamp socket electrical contact 10 is connected to a power source and contacts the contact ends 18 of the lamp 12 in the lamp assembly which also includes a reflector member 14. Once in position a copy sheet having a toner image thereon is passed in the direction of the arrow underneath the lamp 12 and across the top of the fuser platen 16.
