The RX is isolated from the switch when it's turned OFF and or for charging. Is it possible you had the switch "ON" or switched it "ON" when charging?

It seems like prudent design of connectors in electrical equipment should observe polarity or be tolerant to reverse polarity. Good design (people friendly design) should never allow plugging the plug backwards to destroy equipment. Was it the charger or the switch that allowed backwards plug in?

It is a problem that JR and Futaba transmitter charging jacks are mechanically compatible but polarity reversed. And then they add diodes inconveniencing everyone. What a poor design. How could they possibly have made the design any more people unfriendly? Seems like the electronic geniuses are severely lacking in people savvy.

My traveling phones can be put in the cradle either way and they charge happily.

A quote from the most useful charging equipment in my shop:
“‘X’ is also goof proof. You cannot harm the charger OR your batteries by plugging anything in backwards! If you believe in Murphy’s Law, this is a very important feature.“
