Abstract
A current sensing device includes an electrically conductive current shunt member (10), and a voltage-responsive member (12). The current shunt member includes a first portion (14) having a free end (20), and a second arcuate portion (16) including an arcuate slot (38) defined by a constant radius (45) centered about the free end (20) of the first section, so that when current is passed through the arcuate section (16), the voltage produced by the shunt (10) may be varied by pivoting the voltage-responsive member (12) retained at the free end (20) of the first member and at the arcuate slot (38), and bridging or spanning between this first free end (20) and the arcuate slot (38). Preferably, the current-sensing member (12) includes electrical or electronic circuitry, for providing an output when sensed voltage, proportional to current through the arcuate portion, exceeds a predetermined level.
