<p>A relay device of the DC contactor type which utilizes a linear 'impact break' method to achieve contact break. An armature (4) has attached at one end a plunger (10) situated at the base of the core (9) of the relay. A first spring (14) serves to provide a biasing force so as to maintain the plunger (10) and the armature (4) in an open state. Attached to the armature shaft (13) at its end opposite the core base (9) is a moving contact disk (21) which is rotatable about the armature shaft (13) which is capable of coming into contact with two stationary contacts (22) so as to complete or close an electrical circuit. A movably mounted second spring (18) is located about the armature shaft (13) and situated between a first washer (19) and second washer (20). The moving contact disk (21), the second spring (18) and associated washers (19, 20) are rotatable about the armature shaft (13). The second spring (18) rotates freely upon its compression.</p> |
