Claims

[Scope of utility model registration request]

The upper yoke _Y2 has an armature holder L on its upper surface and is bent to have an approximately L-shaped cross section;
A lower yoke Y1 is bent into a U-shape so as to hold the bent part of the upper yoke _Y2 at a predetermined gap _, and is loaded between each of the yokes. A wire ring C and return springs Sp ₁ and Sp at both ends thereof.
₂ , and a plurality of fixed movable contacts K between them.
₀ , K ₁ , and K ₂ at their respective lower parts, a boss b fixed to the lower part of one side of the lower yoke Y 1 having a protrusion t on one side, and a boss b fixed to the lower part of one side of the lower yoke Y ₁ and the upper part of the boss b fixed to the armature holder L. an armature A formed in an inverted U shape so that the armature A is restrained and its lower part is loosely fitted into the projection t and comes into contact with the lower yoke, and the armature A is supported by each of the return springs. Each of the movable contacts K ₁ , _K2 are directly driven, and one of the return springs is loaded in a space formed by each U-shaped portion of the lower yoke _Y1 and the armature A.
