  • Method of manufacturing a switch substrate
    Patent number: 5242642
    Abstract: A switch substrate for a switching device that includes an electrical contact brush, the substrate formed with alternating conductive and insulating portions on its surface and having a groove formed between the conductive and insulating portions to eliminate insulating abrasion powder from the surface of the contact brush. The top of the conducting portions is higher than the bottom of the groove but can be above or below the surface of the insulating portions. To form such a substrate, a conductive layer having projections is formed and is engaged with a mold so that the projections are compressed. After the substrate is removed from the mold, the compressed projections extend to their actual height.
