A microswitch on a newer game does not register.
Microswitch not working
Cause: Its actuator wire is bent so the ball no longer presses it far enough.
Checks
- Press the actuator and listen for the click.
- Check the switch with a meter.
Fix
- Bend the actuator back into position or replace the switch; microswitch contacts cannot be cleaned or gapped like leaf switches.
