Claims

[Scope of utility model registration request]

(1) An electromagnetic switch comprising a solenoid coil and a movable iron core housed in a switch housing that also serves as a magnetic circuit, characterized in that the switch housing has a semicircular two-part structure.

(2) When the switch housings are assembled together,
It constitutes a cylinder with a bottom, and the movable core is loosely fitted into the through hole provided at the bottom so as to be able to slide in the axial direction, and the flange portion of the fixed core is inserted into a part of the spigot formed at the open end. The electromagnetic switch according to claim 1 of the utility model registration claim, wherein the electromagnetic switch is fitted with concave and convex portions so as to be fastened.

(3) The movable iron core is provided with a flange at the bottom, and the flange is secured to a through hole provided at the bottom of the switch housing so that it cannot be removed. Electromagnetic switch described in section.

(4) A movable contact shaft is inserted through the center of the fixed core, and is configured to be moved and biased by the movable core so as to close the fixed contact of the switch cap device fixed to the protruding side of the shaft. An electromagnetic switch according to any one of claims 1 to 3 of the claims registered as a utility model.

(5) The electromagnetic switch according to claim 4, wherein the switch housing is fitted together with the flange of the fixed iron core into a part of the spigot of the switch housing.
