摘要

An improved reversing hermetic switch, of the type whose tubular drive section is inserted in the gearbox in direct contact with the lubricant thereof, said tubular tubular portion, of reduced diameter, extending into a cylindrical cavity like a glass that it houses the interrupter arrangement and receives a plug attached to a second semipieza carrier, the terminals, integrating as basic functional elements a cylindrical thrust that is connected telescopically through an elastic means with a rod that acts on a membrane positioned on the bottom of the cylindrical cavity, to which is superimposed a curved discoidal spring, cutter of two peripheral contacts which, in the reversing position of their convexity, rest on a piece that bridges said terminals, essentially characterized in that the disc spring establishes electrical contact by its periphery with one of the termin ales and is endowed with a single contact in its central part; to which is axially confronted the solid fixed contact of the second terminal, the assembly incorporating a circular laminar piece, of plastic material, such as a polyamide, located between the end of the tubular chamber through which the pusher shaft and the surface of the sliding element slide. The rubber discoidal membrane, fixed on its seat by the semi-part carrying the terminals in its mounting position, whose laminar element completely seals the cavity of the interrupter arrangement, also protecting and stabilizing the membrane, by preventing access to it by the inevitable gap in every sliding arrangement, of the hot oil in the gearbox.
