ABSTRACT:
A high-voltage magnetic relay enclosed within a housing of insulating material which contains a gas, such as sulfur hexafluoride. The terminals within the housing extend through its wall and are secured to the housing in sealed relation thereto to prevent gas from leaking from the housing. Leads are connected to the terminals externally of the housing, with insulating material surrounding the leads and being secured by the terminals to the housing. An operating mechanism within the housing shifts a pivoted arm electrically connected to one of the terminals within the housing into and from contact with another of the terminals within the housing.
