Circuit selector

Abstract

A circuit selector, particularly adapted for the control of stage lights and the like. A support frame carries a group of input buss bars that are individually connected to power sources through dimmer control devices. A load control switch corresponding to each connected buss bar is also mounted on the support frame. At least one load slider member is arranged to be repositioned and engaged with a selected one of the input buss bars while making electrical contact through a slide or guide rail for the slider member between a selected input buss bar and the corresponding load control switch. The slider member is yieldably actuated to a circuit making position and is positively latched in a retracted condition to freely move along the guide rail as it is positioned for engagement with a selected input buss bar. The input buss bars are separated by insulator plates, telescoping spacers, and the input buss bars and insulator plates and telescoping spacers are sandwiched together by nuts threaded on the ends of a threaded shaft passed through the interleaved input buss bars, insulator plates and telescoping spacers. The telescoping spacers are used as insulators between buss bars and between the buss bars and the shaft and the spacers insure uniform spacing between adjacent buss bars and insulator plates and proper positioning of the buss bars as they are engaged by a contactor foot of the slider member.
