Abstract
A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point.
