I was on HobbyKing.com looking around and I noticed that they have a 15A regulator, the kind that I'd get to run a 2S lipo on my receiver, with a fail-on switch. I really liked that idea. A switch that didn't close a circuit, but one that would open a circuit....if that makes any sense. Like, most switches are made to open a circuit by default and close the circuit when it's switched. From what I understand, this one works the opposite way. I've seen many switches fail before, and heard of even more failures.

I guess what I'm asking is where can I get these safety switches, and are they really worth it? I'd hate to crash my favorite plane because my SWITCH failed!!

When I am able I will be ordering a few of these [link=http://www.rcaccessory.com/index.asp?PageAction=VIEWPROD&ProdID=83]switches[/link]

Holy crap!! That's an expensive switch!! All I know is that that thing had better work miracles for $25. It does look nice, but my biggest engine is a Saito100...so I don't think I really need that nice of a switch quite yet. Is it fail-on, though?

Considering that switch has a built-in battery meter ($12) and charge jack ($3) I'd say it's not terribly expensive, and is much cleaner than installing component wise.

I am interested in this 'fail-on' switch as well, so anyone with any experience please chime in

I've seen this one used at our field. Very bottom of the page. Pin and flag fail safe. Its used on a 150cc Python biplane.

That's a pretty switch. Quick question though, do you have to have a smartfly reg with that switch or not??

Just guessing, but probably yes. The guy that uses this one in the club also runs the regulators. When you have that much invested in a 150cc plane the cost of a switch like this is nothing. On the other hand, for a typical medium sized arf, would be hard to justify. I check my switches once and awhile using a transformer type of ordital sander. Leave the paper off and just hold it up against the fuse new the switch. I use a led voltage monitor to see if the voltage jumps around. If it does, in goes a new switch.
