Abstract

A magnetically adjustable relay which may have an internally positioned sealed contact system is disclosed wherein the switching element of the contact system is elongated and has one end affixed to an elongated ferromagnetic adjusting plate. The adjusting plate is attached to the coil body by means of torsional cross pieces or bars. The position of the adjusting plate within the coil body can be adjusted by means of an exteriorly applied magnetic field which deforms the cross bars.
