Abstract

Improvements in protection switches for leakage currents with a totalizing current transformer that has primary windings to connect to a current circuit to be controlled and a secondary winding linked to the excitation winding of a trigger electromagnet acting on a reclosing for a connecting device, and with a pushbutton having a fixed contact part and a mobile part and with which a test circuit between the output connection of a primary winding and the input connection of the other primary winding, characterized in that the movable end of an arm of flat, flexible and elastic insulating material, which with its other end faces one side of the junction line between the contact faces of both contact parts, is arranged in the space between them contact faces separated from the contact face of the fixed contact part.
