Claims

[Scope of utility model registration request]

a casing, a self-returning electromagnetic device installed in the casing, and a toggle operation mechanism that alternately positions two stable positions for each reciprocating motion of a movable core of the self-returning electromagnetic device;
A fixed contact provided within the casing; a movable contact that opens or closes relative to the fixed contact for each reciprocating motion of the movable core in conjunction with the toggle operation mechanism; a handle rotatably supported on the housing and having one end connected to the toggle operation mechanism; a window for operating the handle formed in the housing; and a cover removably attached to the window. An electric opening/closing device comprising: a locking means provided on the cover for locking the handle in an open or closed operating position.
