    • A magnetic switch comprises a first frame (110) and a second frame (120), a stationary contact (130) to face the second frame, a movable contact (140) contactable with or separated from the stationary contact, a coil assembly that generates a magnetic force in accordance with a flow of an electric current, a movable unit that makes the movable contact to be contactable with or separated from the stationary contact, a contact spring (165) that applies an elastic force to the movable contact in a direction that the movable contact moves toward the stationary contact, a movable distance limiting unit (170) limiting a movable distance of the movable unit to determine a contact pressure distance that the movable contact contacts the stationary contact and the contact spring is pressed, and a return spring to apply an elastic force to the movable unit in a direction that the movable contact is separated from the stationary contact.
    • 磁开关包括第一框架(110)和第二框架(120),与第二框架相对的固定触点(130),与固定触点接触或分离的可动触头(140),线圈组件,其产生 根据电流流动的磁力,使可动触点与固定触点接触或分离的可动单元;向弹性触点沿方向施加弹性力的接触弹簧(165) 可移动接触件朝向固定接触件移动;可移动距离限制单元,限制可移动单元的可移动距离,以确定可动触头接触固定触点和接触弹簧的接触压力距离;以及返回 弹簧以在可动触头与固定触头分离的方向上向可移动单元施加弹性力。
