Troubleshooting: Switches


Many of our products have physical switches on them to change device behavior.  Unfortunately, we’ve noticed quite a few problems related to these switches.  Over time, sometimes switches fail to behave as you would expect them to.  We suspect this is due to oxidation on the contacts, dust or another slow-acting cause.


Affected Devices

These devices use the switches which are known to have issues:

  • AutoProm / APU1
  • Ostrich2
  • ALDU1



Fortunately, the solution to switch glitching is really easy.  Sliding the switch back and forth vigorously 5-10 times has been successful in restoring normal operation.
