DC SWITCH AND DC BREAKER

摘要

PROBLEM TO BE SOLVED: To provide a small size DC switch.SOLUTION: A case 5 of a DC switch 1 stores two pairs of electric circuits 10a and 10b. The two pairs of electric circuits 10a and 10b which include fixed contactors 17a and 17b having fixed contacts 21a and 21b; and first and second opening/closing units 30a and 30b which include a set of movable contactors 18a and 18b having movable contacts 22a and 22b. The first and second opening/closing units 30a and 30b cooperate with the operation of a handle 15 to open and close the fixed contacts 21a and 21b and the movable contacts 22a and 22b. The two sets of electric circuits 10a and 10b are arranged to be unlevel with a part thereof overlapped with each other in a direction perpendicular to an alignment direction thereof.
