  • Patent number: 4777720
    Abstract: A method for manufacturing a multiple wire brush contact includes the steps of stamping a continuous strip of material so as to define a series of spaced blanks, each including a cross bar and a base mounting plate, separating side carrier portions, welding and soldering contact wires onto the cross bar portions, cutting and forming the contact wiper. The multiple wire brush contact assembly thus includes a base mounting plate that is separate from the cross bar and wire spring and that is used to handle and mount the assembly in a cooperating receiving space in a rotor or other element.
