Lately I have been rewiring Futaba HD or JR Gold switches to have two servo type plugs into the RX and 18 AWG wire to the battery using a Deans 4-pin plug. Works OK.

But since I have to remanufacture them anyway I looked for some good locking toggle switches. The TE Connectivity ALCOSWITCH MTL Green series seem good. If you get the DPDT or 3PDT switches and wire them redundantly they should not fail. Gold over Silver contacts.

MTL306D or MTL206N at DigiKey, Newark, Allied, etc.

I've heard good reports from others who have used this toggle switch as a RX switch. Even has a spec for vibration in the datasheet.

Silver has a lower resistance.

A different way of accomplishing the same thing, look at Perfect Regulator fail safe switches.

Well that is mechanical failsafe but not electronic failsafe. You can blow a MOSFET. But worth looking into. Silver is a better conductor than gold. The gold is just to prevent corrosion/oxidation. Switch/contact gold is an allow of palladium or something to make it hard. Otherwise the switch action would just wipe it off.

The life expectancy of the expensive switch is 4 times the cheap switch.

The Perfect Reg. switch ain't cheap. I think I would prefer the $25 3PDT switch wired in parallel. But some guys just unplug the RX battery.

I had 2 mechanical switches fail on my gassers. Perfect Regulator switches have held up much better, versus a crash they are worth the extra cost.

I've been running switchless for ten years now. No failures. Simply pop off the canopy to plug or unplug the battery. I often leave the model powered up between flights or awaiting my turn at the flight line. No issues.

Enjoy things that money can buy IF you don't lose the things money can't buy.

In line with Tyler I either use no switches or 2 switches (my receiver packs have dual outputs).

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.
