Abstract
An electric lever and sudden break switch, which, independently of being mono, bi or three-phase circuits, is characterized by the fact that the support of each of the mobile contactors consists of a rocker lever on a pair of angular bearings, requested by a spring linked to another lever similar to the first one opposed to it, swinging around another pair of angular bearings arranged in reverse position with the first ones; this second lever, or group of them if there are several phases, is solidary with the control hand and, by effect of the spring, and the positions of the vertices of the bearings of both levers, these tend to be maintained, in two stable angular positions reversed from one to another abruptly, by varying the position of the hand.
