<p>An electrical switch (100, 200, 600, 700) and a circuit breaker (300, 400, 500) are presented herein. The electrical switch (100, 200, 600, 700) includes a graded resistance block (110, 210, 310, 410) comprising a first end (112, 212, 612, 712) having a first electrical resistivity and a second end (114, 214, 614, 714) having an electrical resistivity greater than the first electrical resistivity. The electrical switch (100, 200, 700) further includes a fixed contact (120, 220, 720) electrically coupled to the first end (112, 212, 712) of the graded resistance block (110, 210, 710), and a sliding contact (130, 230, 730) configured to slide over the graded resistivity block (110, 210, 710). In addition to the components of the electrical switch (100, 200, 600, 700), the circuit breaker (300, 400, 500) also includes a forcing mechanism to slide the sliding contact (130, 230, 330, 430, 530, 630, 730) over the graded resistance block (110, 210 , 310, 410, 510, 610) from the first end (112, 212, 612, 712) to the second end (114, 214, 614, 714).</p> |
