A VACUUM INTERRUPTER

摘要

A vacuum interrupter comprising a pair of fixed and movable electrode rods having a flange portion identical shape, a pair of fixed and movable electrodes of the magnetic arc driving type having a central hole and two annular recessed fitting portions of identical depth on the upper and lower surfaces thereof, respectively, and a contact member having a flange portion; the annular recessed fitting portions of the electrodes being formed to match the flange portion of the electrode rod and also with the flange portion of the contact member so that a single form of electrode rods and a single form of electrodes can be used in common in cooperation with the contact member, and the number of elements and the manufacturing cost can be reduced when two different material contacts are used for prevention of fusion sticking.
