Invention classification information

The invention is classified under using blow-out magnet, by magnetic force, By reciprocating armature, Contact arrangements, Magnetic or electrodynamic force, Electrodynamically actuated, Electrodynamic relays, i.e. relays in which the interaction is between two current-carrying conductors, Mechanisms for operating contacts, Relays using the dynamo-electric effect, i.e. relays in which contacts are opened or closed due to relative movement of current-carrying conductor and magnetic field caused by force of interaction between them, Armature is movable between two limit positions of rest and is moved in one direction due to energisation of an electromagnet and after the electromagnet is de-energised is returned by energy stored during the movement in the first direction, e.g. by using a spring, by using a permanent magnet, by gravity. The designated search classifications include Electrodynamically actuated, with electrodynamic opening, Magnetic or electrodynamic force, By reciprocating armature.
