Re: Routine switch replacement
I autopsied the failed Cermark switch after I replaced it. The photo shows that the lead opposite the charge port had been just about worn in two. I lightly tugged on the lead and it came off in my hand, leaving the little wire stubs shown. The case had a hard plastic edge where the lead exited, with no grommet or potting material. Over time, vibration just sawed it in two. One more thing to check on a new switch.

Re: Routine switch replacement
Fromeco are the best,
 if you do not want to go that way I would go with the JR HD switches. I have had three MPI switches either fail or fall apart just after about 20 flights or so, needless to say they went into the trash!

Re: Routine switch replacement
I like to "K.I.S.S", Having had a close call recently with a solder failure in a HD switch harness, I'm seriously thinking of replacing the single 2300mAh A123 pack in my 26cc gasserwith two 1100's and just running two of the HD charge jack switches, a lot of redundancy for the bucks

Re: Routine switch replacement
i wouldn't, nothing like a ignition spike into the reciever to make things really interesting.

Re: Routine switch replacement
I no longer use mechanical switches. Solid-state failsafe switches are the only way to go - like those found in Smart-fly power expanders and regulators, or Fromeco switches, etc.

Re: Routine switch replacement
Hey any switch can fail. They all have solder joints....even fail-safe switches.

Re: Routine switch replacement
Bingo
 I'll go with the redundancy provided by two good quality switch harnesses in parallel. Pete

Re: Routine switch replacement
But you are pulling more power from just 2 batteries.
