022 Switch only works one way

@Scotten posted:

I recently purchased several 022 switches.  One of them only works one way and not the other.  I checked all of the wiring for continuity and did not find any issues.  The ;eft post seems to be deal.  Any suggestions?

Note, the power to the coil goes through the sliding contacts. This is one possible cause why it would be dead in one direction.

I would think that the internal contacts in the motor could be one source of such a problem. This is because they are the path that connects and disconnects the coil for a direction to prevent burning out the coils with a stuck trigger (example a car or axle parked in the anti-derailing sensing zone).

I would clean those bronze and sliding contact points on the PCBs

Thanks to @ADCX Rob for posting diagrams in this topic https://ogrforum.com/...9#172048746084942999

Also, while this is the older 022, the basic diagram is still valid. Those strap contacts that slide against the PCB are again, what connects the coil and disconnects the coil.
