A high voltage magnetic relay is enclosed by an insulating housing containing a gas such as sulfur hexafluoride under pressure. The switch terminals removably extend through a wall of the housing and are sealed. The magnet structure is removably connected to the housing by a sealed joint. A fill valve removably extends through a wall of the housing and is sealed thereto. The armature shifts a pivotal arm in the housing between open and closed contact positions.
