Claims

[Scope of utility model registration request]

(1) In a multi-pole switch connected to a distribution line having a neutral wire and a plurality of voltage lines, a plurality of main contacts that operate in conjunction with each other to open and close at least the voltage wire and the neutral wire A multi-pole switch characterized in that a sub-contactor which is connected and can be operated independently of the main contactor is disposed in the same housing.

(2) The sub-contactor includes a fixed contact member divided into two or more parts, a movable contact member that faces the fixed contact member and moves toward and away from the fixed contact member, and a movable member that can be manually operated from outside the casing. A multi-pole switch according to claim 1, which is characterized in that:

(3) A movable element having one end protruding outside the casing and the other end having a movable contact member that moves toward and away from the fixed contact, and a locking device that locks the movable element in a predetermined position. A multi-pole switch according to claim 2 of the utility model registration claim, characterized in that:

(4) The multipolar switch according to claim 2 or 3, wherein the fixed contact member has an elastic piece in the shape of an abbreviation that comes into contact with and separates from the movable contact member. .
