Electrical switch i.e. circuit breaker, has strip fastened to free end of retaining bracket and comprising fastening end, and input terminal connected with fastening end over conductor piece that has higher conductivity than bracket
The switch (1) has a tripping device comprising a strip (2) made from thermal bimetal and shape memory alloy. The strip is fastened to a free end of a retaining bracket (4) supported at a support end in a movable manner. The strip stays in effective connection with a latch (8), and a current path runs between input and output terminals (9, 10). The terminal (9) and a fastening end (3) of the strip are connected over a conductor piece (11) i.e. conductor strip, that has higher conductivity than the bracket, where the bracket is made from steel and the conductor piece is made from copper.
