Abstract
A relay device utilizing a linear 'impact break' method for contact break. An armature shaft has attached at one end a plunger situated at the base of the relay core. The armature has a terminal end portion at its other end. A spring provides a biasing force to maintain the plunger and armature shaft in open state. Resiliently mounted on the armature shaft adjacent its end opposite the plunger is a movable contact disc rotatable about the armature shaft for coming in contact with two stationary contacts in the closed state. The armature shaft towards its plunger end extends into an armature travel cavity. The armature shaft towards its movable contact end extends into a chamber open to the armature travel cavity. A movably mounted further spring is located about the armature shaft between the contact disc and a stop on the armature shaft. The further spring rotates upon its compression to rotate the contact disc to vary the position of contact during a plurality of closing operations. The terminal end portion extends beyond the contact disc upon closed state, and is accelerated by expansion of the further spring to impact the contact disc to provide the contacts open state. All moving parts of the relay are hermetically sealed from the outside atmosphere.
