Electromagnetic relays (relays using the dynamo-electric effect H01H53/00) > Non-polarised relays > with single armature; with single set of ganged armatures > 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
