ABSTRACT:
A screw operated electrical contact device having at least one pair of electrical conductors disposed on and projecting evenly above a dielectric surface, an insulation gap separating said conductors from each other, a nut attached to or part of the dielectric surface, having a center axis perpendicular to the surface aligned with the gap, a screw in threaded engagement with the nut, the screw being adapted to be moved along the length of the axis as it is rotated about the axis in the nut, and a contact dimensioned to bridge the gap, mounted fixedly and insulatingly in the screw, adapted to connect the conductors electrically together by exerting simultaneous pressure on both of them as a result of advancement of the contact toward the surface caused by the screw being rotated about the axis.
