Claims

[Scope of Claim for Utility Model Registration] An electromagnetic device having a fixed contact with a fixed contact, a movable contact with a spring property with a movable contact, and an armature that performs bistable operation by inserting a permanent magnet in a magnetic circuit. and a movable frame that drives the movable contact in response to an armature, and when the movable contact is lifted off by the movable frame, an intermediate portion thereof comes into contact with a support base to increase a spring load, The support base has a plurality of abutting pieces whose spring load characteristics can be selected, and the unselected abutting pieces are formed to be removable.
