Claims

[Scope of utility model registration request]

(1) A self-returning electromagnetic device, an idler that interlocks with the movable core of this self-returning electromagnetic device, a rotor that rotates clockwise and counterclockwise due to the engagement of this idler, and A toggle spring with one end stretched, a movable contact rotatably supported by the rotor and moving toward and away from the fixed contact, an auxiliary switch operated by the movable contact, and a lead for the auxiliary switch. The movable contactor is provided with an auxiliary switch terminal connected to a wire and a circuit terminal for operating the electromagnetic device, and is operated by the toggle action of the rotor and the toggle spring, which rotate when the self-resetting electromagnetic device is driven. In an electrical switchgear that connects and separates the terminal from the fixed contact to the fixed contact, the terminal is located at the lower end of the operating circuit terminal of the electromagnetic device, has a recess formed in the side wall of the case, and is screwed onto the auxiliary switch terminal. An electrical switching device characterized in that the auxiliary switch terminal is fitted into the recess so that the screw can be rotated obliquely from above the outside of the recess.

(2) The electric switchgear according to claim 1, wherein the auxiliary switch terminal and the operation circuit terminal are electrically insulated by the inner wall and bottom wall of the recess.

(3) The electric switchgear according to claim 1 or 2 of the utility model registration claim, wherein a terminal cover covering the upper surface of the operation circuit terminal is detachably provided between both sides of the case. .

(4) Utility model registration claims in which the auxiliary switch is fitted and held in the case, and the opening/closing operator of the auxiliary switch that the movable contact comes into contact with is slidably supported by the case. The electric switchgear according to item 3.
