    • H01H51/04—Non-polarised relays with single armature; with single set of ganged armatures
    • H01H51/06—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
    • H01H51/10—Contacts retained open or closed by a latch which is controlled by an electromagnet
