ABSTRACT:
Illuminated sighting structure for archery bows wherein a bow attachment bracket is provided not only with sighting units but also with lighting means for selectively illuminating such sighting units, especially the tips thereof. The bow-sight illumination structure itself is designed to have a plastic non-conductive case and allowing for on-off conditions of the light employed by a non-conductive element being interposed in the electrical circuit, which, when compressed, will complete such circuit. This is preferably accomplished by a metallic disc or element within a non-conductive ring, the disc being of less width than the ring. An adjustment screw accomplishes the width-wise compression of the ring, for conduction purposes, and also a backing off such that the ring by its nature expands so as to separate the electrical elements of the lighting circuit.
