Abstract

207,016. Cox, F. H. W. Nov. 1, 1922. Keyboard switches; switches, latching and unlatching; contacts.-Relates to illuminated signs of the type in which a field of lamps is selectively illuminated by operating switches correspondingly arranged, and comprises a field of switches having spring-controlled buttons b which when depressed are retained by pivoted spring catches g engaging a plate h. The lower ends of the buttons make contact with heads i<2> resiliently mounted on stems i, thereby closing the circuits of corresponding lamps d, the plate h being connected to one main; or the buttons b may depress live springs on to the heads i<2>. The buttons b are selectively depressed by drawing the finger or a stylus over them or otherwise, and they are all released together by sliding the plate h from right to left. According to the Provisional Specification a block formed with a design in relief may be moved over the field of switches, the plate h being kept the release position.
