1. A relay, comprising:
an electromagnetic drive unit with a rotatable armature and a yoke, the rotatable armature comprising a first magnetic contact region, the yoke comprising a second magnetic contact region, the first magnetic contact region being in touch with the second magnetic contact region in a first state of the relay; and
at least one immovable first electric contact and a moveable contact arm with at least one second electric contact, the first electric contact contacting the second electric contact in the first state,
wherein the rotatable armature is connected to the moveable contact arm via a shaft, and
wherein the shaft is embodied as a torsional element, thereby allowing the rotatable armature to rotate with respect to the movable contact arm through the torsion of the shaft.
