The contact members CM1, CM2 provide electrical contact in a first stable state and are open in a second stable state. The slider SL with the magnetically conductive armature AM may be moved between two stable positions and the slider SL may thus break the electrical contact between the contact members CM1, CM2 in one stable position. A permanent magnet PM arranged with magnetic conductive elements ML1, ML2 for generating a magnetic flux to magnetically attract the armature AM of the slider SL to hold the slider SL in a stable position with the contact members CM1, CM2 open. An electromagnet EM or solenoid, preferably sharing a magnetically conductive element ML1, ML2 with a permanent magnet PM, is used to switch between stable states by being energized by an electric current to attract the armature AM of the slider SL or to counteract the attractive force provided by the permanent magnet. The electromagnet EM should be strong enough to counteract the magnetic attraction of the permanent magnet PM in the off-state. The contact members CM1, CM2 are designed such that the repelling lorentz force acts to force their electrical contacts against each other, allowing the relay to be used for high currents without damage problems. A relay may be integrated in the meter to allow remote disconnection of the delivery of power to the consumer.
