Claims18
A relay comprising:
- a magnet armature comprising a magnetic core;
- a permanent magnet secured to the magnet armature for identifying a position of the magnet armature, wherein the permanent magnet is a ring magnet with an opening;
- a magnetic sensor configured to detect a magnetic field of the permanent magnet;
- a hermetically sealed housing, wherein the magnet armature and the permanent magnet are arranged inside the housing, wherein the magnetic sensor is arranged outside of the housing, wherein the magnetic sensor is fixedly connected to the housing, and wherein the housing is configured to be filled with a gas;
- and
- an exhaust tube extending at least intermittently into the opening in a first position of the permanent magnet.

A relay comprising:
- a hermetically sealed housing configured to be filled with a gas;
- contacts located at a first side of the housing;
- a magnet armature comprising a magnetic core and a permanent ring magnet with an opening secured to the magnet armature for identifying a position of the magnet armature, the magnet armature located at a second side of the housing;
- a movable contact arranged at a second axial end of the magnet armature opposite to a first axial end where the permanent magnet is arranged, the movable contact configured to contact the contacts in an active state and galvanically isolate from the contacts in a rest state, wherein the housing surrounds the magnet armature and the contacts completely;
- a magnetic sensor configured to detect a magnetic field of the permanent magnet, wherein the magnetic sensor is fixedly arranged outside the housing;
- and
- an exhaust tube extending at least intermittently into the opening in a first position of the permanent magnet, the exhaust tube connectable to a chamber configured to be filled with the gas inside the housing where the contacts and the movable contact are located.
