Abstract

Improved electrical switch, of the type of rapid opening of the circuit, whose rupture is established in two points of the device, determined by pairs of contactor buttons, essentially characterized in that one of the buttons of each contactor pair is integral with a fixed metal block, housed in a cavity formed by the body of the switch and subject to it by means of retention located at the base thereof, said block of screws constituting connection terminals being carrier, while the other contactor button is integral with a mobile member constituted by a rigid metallic plate, longitudinally arranged and with transverse movement, supported by a centrally located insulating piece in the form of a vase and with axial movement also perpendicular to the base of the switch, inside which the head of a helical spring of antagonism is housed, which tends to raise the contactor member, separating it from the fixed contacts, figure on the other side of said member a second helical spring, inserted in a lug derived from the insulating vessel part, serves for the transmission of the movement to the mobile contact member, determined by an articulated device constituted by a contact-bearing component that is supported on the head of the second spring and is articulated, by means of a transverse pin, to an arm-connecting rod, in turn articulated to a driving handle, also movable with respect to a transverse and emergent pin through an opening made in a cover that it serves at the same time of retention and stop in each one of the two positions of the actuating handle.
