Claims

[Scope of utility model registration request]

(1) In a DC electromagnetic contactor having a fixed contact and a movable contact having fixed contacts connected to each other, the arc generated between the two contacts is driven and extinguished by the magnetic flux of a permanent magnet. The contact is bent into a U shape, and both U
A DC electromagnetic contactor characterized in that the permanent magnet is attached between the U-shaped legs with its magnetic pole facing toward the side opening of the U-shaped leg.

(2) Utility Model Registration In the item described in claim 1, the leg on the side where the contact of the fixed contact is joined to both magnetic poles of the permanent magnet is sandwiched, and the leg is extended in the length direction of the said contact. A DC electromagnetic contactor characterized by having a magnetic pole plate higher than its height attached.

(3) In either of claims 1 or 2 of the claims for utility model registration, a permanent magnet has a part of one magnetic pole cut out, and a fixing device provided in a case housing the contactor. A DC electromagnetic contactor characterized in that the contactor is inserted into notches of different sizes in the interpole insulating walls on both sides of the contactor.
