Abstract

1. Differential trip device having a test device actuated by a push button (10) for simulating a differential fault, comprising a switch with a movable contact shaped as a spring blade (32) and moved towards the closed position by the push button (10), characterized in that said spring blade (32) is housed into a hole (20) extending longitudinally inside the push button (10) in the push direction of the button, that the spring blade (32) is retracted inside said hole (20) in the rest position of said button, interposed between the hole (20) bottom (28) and a fixed abutment (36), and that depressing of the button (10) causes the coming out of said hole (20) of the spring blade (32) and to come in the closed position.
