Abstract (en)
An electric switch having a contact arm (15) mounted for movement about one end (17) whose contact (19) is disengaged from a fixed contact (5) of the switch by movement of the armature (45, 47) of an electromagnetic actuator (1). The actuator armature is arranged to contact the arm only after the armature has travelled some distance and thereby gained appreciable momentum, and the point of contact between the armature and contact arm is further from said one end of the arm than the contact on the arm, thereby more effectively to open the contacts in the event of any minor welding together of the contacts.
