    Got the kids an air-hockey table for Christmas. The Table itself seems
    first rate for a home unit, but I'm disappointed in the scoring sensors.
    These consist of a micro-switch with a spring steel arm/actuator which the
    puck is supposed to close each time it passes through the drop chute from
    the goal.

    There have been several problems, but the biggest is inconsistent scoring,
    that is the switch doesn't close some of the times. I've tried adjusting
    this by bending the arm a bit, but it seems that merely by passing through
    the chute the puck re-forms the arm to the old inconsistent position.

    So I was wondering how involved it might be to replace this switch with a
    photodetector sensor?
    Any ideas, or suggestions of where to look?

    Thanks, Paul

    Omron makes some nice sensors...
    The distribute these just about everywhere so just google around to find a
    distributor after you have made your selection......
