Abstract:
The purpose of the present invention is to provide a disconnector with which it is possible to mitigate the electric field of a fixed contact piece even when a shield molded from resin is not disposed, the disconnector being made smaller than in the past. In order to resolve this problem, this disconnector comprises a movable contact piece and a fixed contact piece, the fixed contact piece having a bifurcated portion, a movable conductor that has a width substantially equal to the gap of the bifurcated portion being disposed at the tip-end side of the bifurcated portion when the contact of the movable contact piece is open, and the tip-end side of the movable contact piece being pinched when the contact of the movable contact piece is closed.
