ABSTRACT:
An oil-immersed switch characterized by movable contacts mounted on a piston for movement in a cylinder for forcing oil or dielectric fluid through stationary contacts for extinguishing any arc during opening and closing of the contacts, and whereby any arcing generated during closure of the contacts generates gas pressure which acts upon a piston for aiding enclosure of the contacts.
