Abstract:
A electrical conductor relay, comprising:a non-conducting, combination chassis/bobbin assembly including a base portion, a bobbin portion, and an upper portion, the upper portion having a window and a plunger slide passage formed therethrough, the plunger slide passage communicating with the window, the base portion and the bobbin portion having a central core passage formed therethrough which extends into the window of the upper portion; an electromagnetic coil located around the bobbin portion and a magnetic metal core located in the central core passage, with a portion of magnetic metal core extending up into the window of the upper portion; a first electrode and a second electrode attached to the combination chassis/bobbin assembly, the first electrode having a first electrode contact, the second electrode having a top end; a plunger slide member that is adapted to move within the plunger slide passage and having a magnetic metal plunger plate affixed to a bottom thereof, the magnetic metal plunger plate being movably located in the window in the upper portion and spaced above the portion of magnetic metal core extending up into the window; a conducting armature with a fulcrum end with a biasing means engagement extending rearwardly therefrom, and a front end with an armature contact on an underside surface thereof, the armature being pivotally engaged with the plunger slide member, the fulcrum end pivotally contacting the top end of the second electrode with the biasing means engagement extends rearwardly therefrom; and a biasing means that engages the biasing means engagement which tends to raise the front end of the armature, thereby raising the armature contact away from the first electrode contact when the electromagnetic coil is not energized.
