摘要：
Magnetic attractive force of a magnet exerted on a movable contact in a sealing case through yokes changes as a result of movement of a magnetic shunt element induced by movement of a movable element located outside the sealing case. As a result, the movable contact can be brought into or out of contact with a stationary contact without involvement of entry of the movable element into the sealing case.
