Abstract

833,599. Cam-operated switches; regulating switches. JENNINGS MUSICAL INDUSTRIES Ltd. July 17, 1958 [Oct. 31, 1957], No. 34054/57. Class 38 (5). A switch suitable for use with electric musical instruments comprises a slidable hollow bar 1 having a roller 4 which engages teeth 7 in the base of a U-shaped frame 9 by the action of a spring 6 on the roller shaft 5. An insulating bridge 10 has movable spring-wire contacts 11 each carrying a button 13, which is forced up by an operating member 14 fixed to the shaft 1, to cause contact 11 to engage a fixed wire contact 12.
