brake light switch

[JackConrad]

David,
    Sounds like any N.C. pressure switch will work.  Might check at a truck parts supply place for an air brake switch.  Should be reasonably priced. Should have contacts that are closed until air pressure reaches approx. 60-65 PSI.  Jack

Dave, If your switch is like on my Eagle it should be a Bendix SL-4 stop light switch that you can pick up at any truck parts place. Do a Google on that part and you should get a picture.
