Abstract

Improvements in electrical switches and circuit breakers with damping resistance, characterized by the fact that the resistance is constituted by a thin film of negative electric transmission coefficient at normal temperature and developed positively directly to the degree of heat reached, arranged on a support piece of insulating material and good heat conductivity, precisely in the area exposed to the heat generated by the rupture arc, all in such a way that the resistance of the film is weakened under the effect of heating produced by the said rupture arc, causing the cooling subsequent to the extinction of the arc, the return of the resistance to its insulating state.
