Abstract
In a relay construction, an insulate coil form having a through bore and a coil wound thereon is fixed to an insulate base by a fixed core part which straddles the coil form and is fastened to the base. The fixed core part has an opening aligned with the bore in the coil form and a plunger or movable core part is mounted for linear reciprocating travel in said opening and bore. An armature in the form of an obturator-type strip of spring metal has one end fastened to the base beneath the coil form and extends outwardly and upwardly from the base in a continuous arcuate bend to its other end which lies above the fixed core part and is fastened to the upper end of the plunger. The obturator strip carries a contact proximate the apex of its bend which tangentially engages a fixed contact leading to an output terminal when the relay coil is energized to magnetize the fixed core part and thereby cause the plunger to move downwardly further into the bore in the coil form.
