Abstract
597,489. Switches held set and freed mechanically; switch covers. WALLIKER, G. S. Aug. 21, 1945, No. 21379. [Class 38(v)] The circuit of an electric lamp b of the fluorescent or luminous gas discharge type is automatically made when the cover d is secured in position, and is broken when the cover is removed. A screw e on the cover screws into a sleeve f on the lamps mounting panel g and forces the contact-carrying bar h upwards by means of a spring in sleeve f, thereby making contacts i. A press-button switch may also be included in the lamp circuit.
