Abstract
Abstract Modular electrical shunts for use in programming electric/electronic equipment are disclosed comprising a electrically insulating, substantially rectangular base having two end walls, an anchor pivot, a pair of parallel grooves adapted to slidably receive male terminals and a spring stop recess. An electrically insulating, substantially rectangular cover having a recess is bonded to the side of the base. A torsional spring contact is disposed between the base grooves adapted for torsional bias induced by the insertion of male terminal pins into the base grooves. In a second embodiment a bowed leaf spring contact, adapted for bias induced by the insertion of male terminal pins into the base, fits in the cover recess. Other embodiments relate to ganged shunts for selectively shorting combinations of male pins. The base and cover end walls may have horizontal grooves and bevelled edges on their external sides adapted for loading the shunt into a dispenser cartridge.
