Abstract

An electrical switch consists of a differential tripping circuit (2) with magnetic torus which is mounted on a data processing electronic card (3) and combined with a mechanical open/close mechanism (4) with an operating button. The assembly fits into a case (1) which has an aperture (21). The aperture (21) enables a spring (19) to be placed into a housing (18) after full switch assembly
