Abstract
980,628. Press button retractive switches. V. & E. FRIEDLAND Ltd., and J. DOGGART. Oct. 10, 1962 [Oct. 11, 1961], No. 36563/61. Heading H2B. A switch has a transparent or translucent housing 11 with screwholes 15 for screws 16 for attaching it to a door &c., an opaque cover 12 covering most of the housing, a push-button 23 slidable in the housing and a lamp 35 held in the housing by upstanding spring arms 34 of a pair of contacts 32, 33 which are actuated by the push-button 23. An annular gap 22 may be left in the cover 12 surrounding the push-button and a gap 46 near the base of the housing may be left so that light may be transmitted through these gaps. A compression spring 36 returns the push-button to its unoperative position. In another embodiment, the lower portion of the housing is left uncovered so that a name plate may be illuminated, Figs. 5, 6, 7 (not shown).
