| 摘要 |
The invention relates to a switching device (1), preferably a power switch, comprising at least one input terminal (2) and at least one output terminal (3) for connecting electrical conductors, and a first switching contact (4) and a second switching contact (5), said switching contacts (4, 5) closing, in a closed position, a current path between the input terminal (2) and the output terminal (3). An overcurrent release device is provided for separating the first switching contact (4) and the second switching contact (5), said overcurrent release device (6) comprising at least one bimetal element (7) which is heated by the electrical current conduction. In order to improve the precision and the degree of reproducibility of the triggering of the switching device, and the adjustment of the overcurrent release device, at least one heat insulator (9) is arranged in the region of a fixing point (8) of the bimetal element (7), in order to reduce the heat dissipation from the bimetal element (7).
