Abstract
A relay includes an electromagnetic drive unit with a rotatable armature and a yoke. The rotatable armature includes a first magnetic contact region and the yoke includes a second magnetic contact region. The first magnetic contact region is in touch with the second magnetic contact region in a first state of the relay. The relay further includes at least one immovable first electric contact and a moveable contact arm with at least one second electric contact. The first electric contact contacts the second electric contact in the first state. The rotatable armature and the moveable contact arm are positioned together on a shaft and the shaft is embodied as a torsional element.
Claims15
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.
A relay, comprising:
- an electromagnetic drive unit with a rotatable armature and a yoke, the rotatable armature comprising a first magnetic contact region and a second magnetic contact region, the yoke comprising a third magnetic contact region and a fourth magnetic contact region, wherein in a first stage of the relay, the first magnetic contact region is in touch with the third magnetic contact region and the second magnetic contact region is in touch with the fourth magnetic contact region;
- 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,
- 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.
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,
- 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, and
- wherein torsion of a portion of the shaft disposed between the moveable contact arm and the rotatable armature allows rotation of the rotatable armature with respect to the moveable contact arm.
