摘要

Improvements in the construction of industrial type switches, according to which the assembly comprises a box in which the corresponding circuit breakers and the pair of clamps that constitute the fixed contacts of the circuit-breaker are conveniently isolated and connected, the clamps remaining integral with the circuit breaker. Each pair of arrangement to be blades integral with a transverse axis that can rotate freely, with movements determined through an external control member, essentially arranged on the cover of the referred box, whose organ is related by means of a set of levers with a mechanical device supported by one of the side walls of the box and subjected to the action of a strong spring that drives it constantly to adopt one or the other of two limit positions, relating in turn this mechanism with the shaft integral of the blades, so that the movements of that one are transmitted to this one impelling it turns sharply to move from one to the other of its two limit positions, in one of which the blades are inserted in the clamps, closing the circuit, while in the other position are those away from them, opening the circuit; and a fixed stop being provided to the box in which, in the closed circuit position of the switch, one of the levers that transmits the movement of the control member latches, preventing the opening of the cover.
