发明名称 Method of manufacturing a movable contact unit to be disposed close to a magnetic sensor
摘要 A method of manufacturing a movable contact unit includes manufacturing a movable contact, sticking the movable contact to a base sheet made of insulating resin, and applying demagnetization to the movable contact so that the residual magnetic flux density is smaller than the operation magnetic flux density of the magnetic sensor. In manufacturing the movable contact, elastic metal plate material is processed into a downwardly opening dome shape to form the movable contact. In a method of manufacturing a switch panel, the movable contact unit is overlaid on a wiring board having a contact, including pair an outer fixed contact and a central fixed contact, that corresponds to the movable contact so that the lower end of the outer periphery of the movable contact is mounted on the outer fixed contact.
