Abstract

1. An electric contact arrangement, to be operated magnetically, with two magnetically, electrically conductive contact springs forming a substantially closed magnetic circuit, each of which contact springs is fixed by one leg (4, 5) to an opposite side of an insulating spacer (6), and each connected to an electric terminal conductor (13, 14), and is opened or closed with elastic deformation depending on a magnetic field passing through them, characterised in that the contact springs consist of two U-shaped bent strips (1, 2) with their free ends inserted one in the other, and in that two legs (7, 8) belonging to different ones of the U-shaped bent contact springs, at least one of which is not fixed to the insulating spacer (6), lie alongside each other at a distance such that they touch or move apart with elastic deformation of at least one strip (1, 2), depending on the magnetisation of the magnetic circuit formed by the contact springs.
