Where can I buy the pin flag switch that fromeco use in bulk? I can't seem to find a suppler. Can someone point me in the right direction.

The switch part is just a 1/8 inch phono jack that you can get at Radio Shack. You would have to come up with your own pin. A piece of 1/8 inch music wire would be fine but if it is humid it will rust.

Not to pick nits, but that would be an 1/8" phone jack . . . phono jacks are those horrific pieces of **** that we used to have to plug in our turntables with - sloppy center pin, and 4 (or so) "ears" around it for the ground conductor . . . no way a pin would make contact in one of those.

I wouldnt use a piece of wire. Get the 1/8 plug and solder it closed and put the cap back on.

Pepsidan,

Thanks, I know there is a ton of rc market places that use this switch. They are not the ones making the switch. They are buying the switch from some supplier. Then putting wires on it, so they can sell a product. I'm looking for where they are getting it. Keep the ideals coming.

Thanks

Yup, cheap miniature jacks used on computers, headphones etc.

A mono one will just have tip and sleeve connectors. the appropriate jack-plug will open the circuit (pulling the plug out will normally short the sleeve to ground...or in this case, allow the 2 sides to complete the circuit.

CAUTION...these things aren't really designed for high -current applications and could get hot or melt, if undersized.there are various standard sizes,up to 1/4" (commonly used on electric guitars,microphones, footswitches and other stuff that gets a bit of abuse!

I'd be contacting the manufacturer direct, if you want commercial quantities. It's unlikely to be stocked by the big electronic parts distributors,such as MOUSER,as it's too specialised in application.....but you never know!

Actually, on the Fromeco's, I am not sure that they use an aux contact at all, but rather, they switch the power electronically in the regulator - there is still a small drain on the battery (as per their docs) even with it off. In that case, the pin is most likely just making contact in a normal jack, and the closure is what makes the reg turn off. It also explains how it is declared "failsafe" - an open circuit turns the regulator *ON*, so that any in-flight failure of the switch or lead, cannot turn it off.

Granted, that game changes when you roll your own, but that's how the commercial one is setup.

Yes tadawson is right, it is a phone jack. Similar to this one, but has internal switch so when you put the plug in it opens the switch. It is made for headphones so when you plug in the headphones it turns off the speakers. And they are very cheaply made. I don't personally understand why anyone would want to use them, I just use a switch in place of it. You still get the failsafe feature, just remember on is off and vice versa
