Abstract:
A breaker switch arranged between two studs of at least one connection means connected between outer terminals and an electric power supply or consumer device, contained in a container and whose internal operating temperature must not exceed a critical value &thgr;1, wherein a wall of said container carriesa receptacle, intended to accommodate a thermofusible composition having a softening temperature &thgr;1, and having heat transmission means with the container, and a flexible metal strip, interposed between the two studs, electrically breaking said connection means, said flexible strip extending above said receptacle, being fixed by one of its ends to the wall of the container and being provided in a free portion thereof with means for anchoring thereof in said thermofusible composition, said flexible strip being able to occupy a first position called the closed position, in which the anchoring means are held in the thermofusible composition while said free portion is bent towards the wall of said container to establish an electric contact between the studs, and a second position called the open position in which it is released from the thermofusible composition by its elastic return force thereby opening the contact between the studs when the temperature of the container becomes higher than the softening temperature &thgr;1 of the thermofusible composition.
