Claims

[Scope of utility model registration request]

A synthetic resin molded case that is attached to a vertical wall and has a guide window on the front side and an opening on the back side.
Fixed contacts are arranged opposite to each other on the front side of the case with the guide window in between, and a movable contact is guided by the guide window of the case so as to be slidable in the front and rear direction and bridges and opens the fixed contacts. a supporting contact support;
A movable core connected to the contact support and a fixed core disposed opposite to the movable core close an opening on the back side of the case and a clamp-type electromagnet housed in the case, and connect the movable core to the movable core through a cushion. In an electromagnetic contactor comprising a back cover that is in pressure contact with the fixed core of the electromagnet, a step is formed on a surface of the back cover that is in pressure contact with the fixed core, and that starts from a portion below the axis of the electromagnet and is recessed with respect to the pressure contact surface. An electromagnetic contactor characterized by being provided with.
