Abstract
A miniature armature relay having a substantially flat header and a cover therefor. Attached to the header is an electromagnetic operator which comprises an electromagnetic winding and a reciprocatable armature therewithin which carries a disc-shaped contactor. Mounting lugs are fixed to the header on opposite sides of the armature, and individually carry a stationary contact to be engaged by the contactor. Alignment means comprising a pair of anchor lugs on opposite sides of the armature, and a flexible member secured to the armature and such anchor lugs is also included. A biasing spring urges the armature to retracted position and the electromagnetic operator overcomes such spring in response to energization of the winding thereof.
Claims4
A miniature armature relay comprising in combination,
- a generally flat coplanar header and a cover therefor,
- an electromagnetic operator fixed to said header comprising an electrically energizable winding and means affording a magnetic circuit including an armature,
- alignment means comprising a pair of anchor lugs fixed to said header on opposite sides of said armature and a flexible member fixed to said armature and to said anchor lugs to limit said armature to rectilinear movement,
- biasing means urging said armature in one direction, the electromagnetic operator being operable to overcome said biasing means to move said armature in the direction opposite to said one direction,
- at least one pair of electrically conductive mounting lugs in said header on opposite sides of said armature,
- a stationary contact fixed to each of said lugs,
- an electrically conductive contactor carried by said armature for reciprocatable movement into bridging engagement with said stationary contacts with corresponding movement of said armature,
- and a mounting terminal for each of said lugs connected in circuit therewith within said header and extending from the edge of said flat header, said terminals being formed with a right angle exteriorly of said header for insertion in appropriate openings in a printed circuit board.
