Claims

[Scope of utility model registration request]

A pair of fixed contact hands connected to the main circuit terminal and provided facing each other at a distance, an interlocking rod connected to a movable iron core, and a fixed contact of the fixed contact supported by one end of the interlocking rod. In an electromagnetic contactor equipped with a normally closed contact constituted by a movable contact bridging through a movable contact; Connect to the circuit terminal, fold the upper side of the U-shape inside the U-shape, attach a fixed contact to the outside surface, and cut the tip of this folded conductor diagonally to form a roughly triangular shape. An electromagnetic contactor characterized in that a notch is formed in a U-shaped vertical portion near the apex of the electromagnetic contactor.
