Hermetically sealed high voltage contactor with improved arc quenching

An electrical switching device, comprising:

• a hermitically sealed arc chamber;
• first and second fixed contacts, each having a conductive path into said hermetically sealed arc chamber;
• a movable contact movable in said hermetically sealed arc chamber between closed state in contact with said first and second fixed contacts and open state where said movable contact is not in contact with said first and second fixed contacts;
• wherein said hermetically sealed arc chamber comprises internal surfaces surrounding said movable contact and further comprises an arc suppression material on one or more surfaces below said movable contact.

An electrical switching device, comprising:

• a hermitically sealed housing comprising a cup and cap hermetically sealed to said cap;
• first and second fixed contacts mounted to said cap and each providing a conductive path from outside to inside said hermitically sealed housing;
• a movable plunger and a movable contact mounted on said movable plunger, said device configured to operate to change the state of said switching device from a closed state allowing current flow through said switching device to an open state which interrupts current flow through said switching device;
• and
• arc suppressing material in said hermitically sealed housing and arranged below said movable contact, said arc suppressing material capable of suppressing arcs formed between said first or second fixed contact and said movable contact.
