Abstract
A vacuum switch which is air operated and which has low contact capacitance, low inductance and low DC resistance. The switch has two fixed contacts and a moveable contact, the moveable contact being insulated from the moveable end structure to minimize coupling capacity between the two fixed contacts. A portion of the fixed contact support structure is cut away to minimize capacitance between the support structure and between the support structure and a ceramic body which is part of the switch vacuum envelope, the ceramic body insulating the contacts and the metal portions of the envelope.
