Status: offline 		decent switches can be had at digikey for less than a dollar and the really good ones can cost 2-3 dollars....only problem is you have to solder them up into a harness by yourself, something it seems most aren't willing to do.

Status: offline 		What I get from all the responses is that the standard 3-wire switch included in complete radio systems for decades, are prone to failure and not to be trusted.

In order to be more self assured, a stout industrial quality switch should be substituted and wired into place using the Rx plug.

The last option is to not use a switch at all, and plug in the Rx battery when ready to go fly.

Thanks everyone, for your thoughts and comments.

Status: offline 		Yep... switches have always been a source of failures and concern and hence why redundancy is the choice for most giant aircraft.

One scheme used many years ago was phono jacks and plugs wired so that inserting the plug disconnected the battery.

Status: offline 		I have used the 1/8" phone jacks as an on/off switch only once. It was on an .049 powered hand launch sailplane. The big red tag hanging from the phone jack hopefully would keep you from launching without powering up the radio . That was in another Galaxy and long, long ago I hate to tell you how many guys in our club tossed their .049 powered sailplane, only to realize "I ain't got it"

I only wish they had an LED indicator built right into the switch plate to indicate when power is on.
FWIW, I did have a solder joint failure in one of MPI's similar switches some years ago, almost lost my 4 Star 60, luckily it was intermittent and I was able to land safely.

Status: offline 		A good switch should have:

1) knife action
2) redundancy - at least 2PDT
3) soldering by orphans that are not on meth

Often overlooked are the crimps on the connectors.

I have not found the aftermarket stuff to be any better than JR or Futaba.

Status: offline 		Sure, with the Powersafe receivers you add the extra complexity of the solid state switching in the receiver, and while more uncommon, a switch harness can possibly short closed. For my money, I'll take two switches, such as the ones from Electro Dynamics in parallel, to a solid state logic switch in the receiver, or one of the popular add-on's that are available (I don't like the parasitic battery drain bit). The failure rate of one of the simple switches such as the ED ones is very low, put two in parallel and the odds of loosing power gets really low. I like simple

Status: offline 		I have used the JR gold switches for the better part of 20 years exclusively without incident on lots of planes from .60 to 1.80 size, fast charging, and high power servos. The extra six or seven dollars is worth it and I always replace a switch after a bad crash. If someday I ever switched radio brands, I would stick with this switch no matter what.

The Noble switch also had a very strong detent ball. The Futaba Heavy Duty switch is knife action DPDT wired in parallel. The detent is a stupid spring thing.

I agree, When I get a new Futaba product their poor quality switch gets thrown in the trash and replaced with a good JR heavy duty switch.

Status: offline 		As a side note, I always mount switches inside the model as to prevent dirt, dust, exhaust residue and moisture from entering the mechanism and fowling the contacts. Personally, I would not turn a plane on and off by plugging in a external lead as in the picture of the quickie plane seen earlier in this thread because of how easy the contacts could become dirty and cause a poor connection. I now always use a pushrod with the pull on/push off convention to activate the switch. Using the same method in every model prevents accidents and confusion. In the few planes that I have had with a switch mounted in the fuse side, I always make sure the switch is mounted so that moving it towards the tail, not the nose, turns the plane on, thus preventing accidental switching off in flight due to the "bug strike theroy" Lastly, anytime a switch is involved in a crash and I suspect that the leads or connectors have been put in any type of strain, I throw away the switch and replace it. I don't make it my job to evaluate wires, connectors, or solder joints that have been subject to a hard hit or shock. I am not a expert in this and i don't take chances. Taking care of your equipment is the biggest part of reliability.
