Abstract
A high current interrupter is enclosed in a sealed enclosure having a pair of axially disposed contacts therein, one stationary and one movable relative thereto. An array of rods or electrodes is mounted near each end of the enclosure, the rods extending toward the opposite end of the enclosure and terminating at a free end short of the opposite end. The arrays are similar in pattern and thus each rod lies between and is spaced from rods extending from the opposite enclosure end. Each array of rods is mounted in a pair of thin spaced mounting plates, which are connected together near the centers thereof. The plates engage the rods near the end opposite the free end, both plates being electrically conductive and being connected electrically to one of the two electrical contacts within the enclosure.
