[TowerTalk] Prop pitch magnetic reed switch

[Tom Rauch]

> I am using a larger prop pitch rotator with a M2 RC2800P-A
controller and Mike's reed switch conversion kit for sending
the digital pulses.  For several days, the rotor was
operating intermittently.. motor would run a couple seconds
and then stop. After a few attempts to get it to run
normally, it would start working again and all was well.

Mel,

In all my experiences with reed switch failures, this has
almost always been caused by contact arcing.

We almost always measure steady state current and do not
measure stored energy that creates a problem at reed closure
or reed opening. Bypass capacitors are a particular problem.
