Abstract

Improvements in the construction of electrical maneuvering devices, according to which each of the independent interruption systems comprising the apparatus is formed by two fixed contacts facing each other, arranged at the ends of respective symmetrical metal pins, conveniently bent and immobilized with respect to the corresponding support casing, between whose contacts is located an independent bridge piece, provided at its ends with respective contacts that in one position rest simultaneously on the fixed contacts referred to, determining the closure of the circuit, and in another position they are housed in these contacts, making the opening; with the essential characteristic that the said bridge piece is mounted on a support of insulating material, from which protrude at its ends, which can slide conveniently guided with respect to the housing between a position, opening the circuit, which is constantly driven to adopt by the action of a corresponding spring and an opposite position, closing the circuit, which is forced to adopt by a cam integral with the rocking body governing the device, which has a protruding apex that in this latter position fits in a corresponding accommodation provided in the aforementioned piece, determining the retention of the set.
