Abstract
A electrical conductor relay. The relay has a unitary, non-conducting, chassis/bobbin assembly with a base portion, a bobbin portion, and an upper portion with a window and a plunger slide passage. An electromagnetic coil is located around the bobbin portion and a magnetic metal core passes through the bobbin and extends partially into the window. First and second electrodes are attached to the chassis/bobbin assembly. The first electrode has a first electrode contact, and the second electrode has a top end. A plunger slide member is positioned within the plunger slide passage and has a magnetic metal plunger plate affixed to its bottom. The magnetic metal plunger plate is movably located in the window and is spaced above the magnetic metal core extending up into window. An armature with a fulcrum end and a rearwardly extending spring attachment end and a front end with an armature contact is provided. The armature pivotally engaged with the plunger slide member. The fulcrum end pivotally contacts the top end of the second electrode. A spring attaches to spring attachment end and tends to raise the front end of the armature and the armature contact away from the first electrode con…
