ABSTRACT:
An improved relay includes a bobbin or spool having dual flanges at each end which include slots for receipt of one leg of an L-shaped armature and core piece. The coil and bobbin assembly including the armature are mounted in a housing on contact pins molded in the base of the housing. An integral armature spring and moving blade contact is also mounted in the housing attached to the armature. One leg of the armature extends along the outside length of the coil and cooperates with a core piece within the spool to complete a magnetic circuit. Upon movement of the armature, the connected moving blade contact provides a wiping action of the movable contact against stationary contact pins thereby effecting efficient making and breaking of a circuit.
