    here's me problem .... have a switch on a Gottlieb scoring motor - inner most at position 3B to be exact, that arcs when the switch is opened by the motor causing the relay controlled by this switch to stay constantly energized which in turn of course keeps the score motor going
    i can physically intervene and stop the arcing allowing the relay to de-energize by placing something between the contacts but so far i have been unable to adjust the switch contacts to a point where they will stop arcing

    do i need to replace the switch? have hit it a number of times with a flexstone and tried repeated adjustments - switch and its actuator look to be the correct factory parts

    this is a new one for me, any ideas on how to solve this are greatly appreciated

    See if pitted. If so, you can use a metal file or just replace contacts.

    took your advice and hit it with the metal file seems to now be OK, arcing has been greatly reduced and relay now shuts off

    thanks for the tip

    Sure thing. I usually follow w/flexstone file just to smooth out. Enjoy.
