Self Retaining Lamp Assembly

The pluggable housing is for an indicator lamp. This is to be assembled in a panel of the type having recessed openings in a front face and terminals extending from a back face.

Housing 10 is in the form of a combined circular lens and a cylindrical grooved body of molded transparent plastic. Within housing 10 is a small lamp
11. Its extending lead wires connect to cylindrical rim terminal 12 and to central end button 13 on end piece 14. Panel 15 is formed with a shouldered recess 16 which has inner spring terminals 17 molded in place. Outer terminal 17 slides in contact over the rim terminal 12 of the inserted housing. The central terminal 17 is pressed against the button 13 of the inserted lamp housing to complete a lighting circuit. It is an advantage to have the lamp housing replaceable from the front of the panel.

The outer cylindrical surface of the housing 10 is grooved or serrated to permit frictional insertion and retention of housing 10 in the panel recess 16, proportioned to hold it firmly in place. Instead of having only intermediate terminals 12 and 13 on housing 10, a pair of terminal pins such as 17 can be attached directly to lamp 11 and extended through end piece 14. In this case, panel 15 need have no fixed terminals but only a circular hole to engage the side of housing 10.
