REFLECTOR: Pitch Trim Mystery

[Ron Brown]

John, 

I agree with TEC:

If the trim switch is in the control stick, it probably has a very low power rating and needs to be actuating relays.  If there is a relay, you need to trouble shoot and determine if the problem is in the relay or the switch.

If your trim switch is mounted on the panel (and involves no relays), then the switch needs to be replaced.

    to do with the switch?

  Use the switch to operate a relay (DPDT).  The relay can handle a larger load then the switch.  Plus, the relay is much easier to replace or trouble shoot in the event of future service.   I have an original military grip w/cooley hat.  It would be tough to find a replacement switch for that, so I elected to use relays to carry both the roll and pitch loads.  Has worked fine for 11 years.
