THERMAL SAFETY DEVICE

摘要

The invention relates to a thermal safety device intended to be fixed to a substrate (2) having a strip fuse (20) comprising a metal strip provided with a first contact zone (23) electrically connected to a first contact pad (8) on the substrate (2) and also provided with at least one other contact zone (22) that can be soldered to another pad (7) on the substrate (2), said strip fuse (20) also including a lever (30) having a free end (36) not connected to the metal strip. According to the invention, the lever (30) generates a rocking moment on the soldered contact zone (22) about at least one pivoting point lying between the two contact zones (22, 23) when the end (36) of the lever (30) is pressed.
