Movable contact unit arrangement including a movable contact unit and a magnetic sensor |
摘要 |
A movable contact unit arrangement includes a movable contact disposed close to a magnetic sensor. The movable contact unit includes a base sheet made of insulating resin, and a movable contact made of elastic metal plate material and having a downwardly opening dome shape. The movable contact is stuck to the base sheet. The magnetic sensor has an operation magnetic flux density during operation, and the movable contact is a demagnetized movable contact so that a residual magnetic flux density of the movable contact is smaller than the operation flux density of the magnetic sensor.
