Abstract

An electrical switch and a circuit breaker are presented herein. The electrical switch includes a graded resistance block comprising a first end having a first electrical resistivity and a second end having an electrical resistivity greater than the first electrical resistivity. The electrical switch further includes a fixed contact electrically coupled to the first end of the graded resistance block, and a sliding contact configured to slide over the graded resistance block. In addition to the components of the electrical switch, the circuit breaker also includes a forcing mechanism to slide the sliding contact over the graded resistance block from the first end to the second end.
