Claims

[Scope of utility model registration request]

In an electromagnetic contactor in which a movable contact is held by a movable contact holder supported on the upper part of the support via a fixing spring disposed inside a hole formed in a support of the movable contact, the movable A horizontal hole is formed in the upper part of the movable contact holder, which is fixed via a fixing spring and a spring receiver inside a vertical hole formed in a column of the contact support, and a contact is provided upward. The movable contact is held horizontally in the hole via a contact spring, and a fixed contact is provided with a contact that can be constantly connected to the contact of the movable contact while the compression spring is compressed. An electromagnetic contactor characterized by being arranged by the following means.
