REFLECTOR: Pitch trim motor

[Al Gietzen]

I too have the Mac-5 grip and switches. I don't recall the motor amperage at
the moment, but I did look it up in the past.  I asked the people at MAC
whether I needed to add a relay for the number I had at the time. They
assured me on 2 occassions that their switches would handle the current.
They also said that the wire sizes specified in the package would work with
that amperage due to the short load time. 

 

Thanks, Kurt.  I guess they should know.  I'm sure the steady state current
isn't an issue for the switch, but I was having second thoughts about the
in-rush current that is getting switched.  And, yes; also wondered about the
#26 wires - shouldn't run more than about 2 amps in that for very long.  I'm
guessing the servo motor is less than 2 amps.  In any case, I'll protect the
switches with transorb across the servo leads.

 

I'm pretty sure I replaced the fuse in my Fluke, but that didn't solve the
problem; although it has been so long ago maybe I don't remember correctly.
But then I remembered it wouldn't respond to the in-rush current anyway.
