Ok i want to get a new switch, i broke my 'invert' switch on my 8103-h.
I looked at radioshack and the switches they had did not seem suitable.
I look at radiosouthrc and they have switches but they all say for various futaba radios, these 2 are the closest matches, will either of these work ?

2 Position LongTX Switch, 7U/8U/9C

3 position long tx switch, 9V/9Z transmitter

Don't tell me you're gonna try flying "switched-inverted" foo.

Sorry, I don't own any JR radio gear. I would suggest trying to remove the old switch first. Then you'll have something to compare the new ones to. Electrically, most of these switches are identical. It'll only be a question of physical dimentions and whether the switch is momentary or not. I assume it's a two-position switch by the picture.

ok, no, i dont use the switch at all, and no im not going to do switched inverted, lol. thats stupid. i just dont want the broken switch, it looks tacky. I have taken the tx apart and the switch looks more similar to the lower one with the blue bottom, the terminals are the same on both of them, and electronically either switch would be fine. My main concern is jus tthat the switch will fit size wise and which might be a better fit since neither of them are identical to my original switch. Yes, it is a 2 posotion round(pole) switch

If it fits, it will work.

Most of those mini bat switches are interchangeable. You can get different lengths of bat, springloaded momentary, 3 position, or 2 position versions of that switch from any good electronic store.

I happen to work in the technical support area of a large electronics distributor, Are there any numbers on the switch? Perhaps a manufacturer stamped on it? What is the actuation style (spdt? on-on? On-Momentary?) I could try to help find one with a little more information.

If you put a 3 position switch on a 2 position circuit, it's not going to work right. The circuitry in the radio will only recognize 2 positions and then you have a wasted position on the switch that may cause problems later. Use a 2 pole if it's 2 and 3 if it's supposed to be 3.
What you want to fit is the threads on the housing and the open/closed positions of the switch.

switch
I would contact a good model shop or email a JR dealer direct.

I have replaced them before and got the replacements fairly quick.

peace of mind knowing for certain you have got the right one.

I totally aggree with Russ Delaney. IVe broken 2 switches over the years on my Futaba radios. I get peace of mind knowing the switch is an exact replacement. Call Horizon!

I would take it back to your LHS. If you bought it there they should send it in to be fixed. I smoked a hitec 4 channel tx and they sent it in for free and had it fixed for nothing.

I dont want to send it in, i dont want to be without a tx, the flying weather is here and i fly almost every day now. I am not worried about doing the repair myself, i can solder pretty decent and my dad solders really really good so thats not a problem. I had always been under the impression that horizon will only repair radios, not send parts. i suppose i will have to give them a call. I also got a generous offer from someone in PM offering me a switch i am waiting for their response to see which switches this person has. When i had the radio apart i didnt note a part number but i really didnt look for any numbers. i can pull it apart again and check ill get back to this. Thanks for the responses guys

I can just about gaurantee you horizon will tell you they want sell you the switch & that you'll have to send it in to them. they claim it's a liability thing. You pay postage both ways plus parts, plus labor, plus down time. General Motors will sell you an ignition switch, brake rotors and pads, steering parts, or anything else you want, but horizon can't sell you a single pole single throw switch because of a liability problem. Call radio South. Oh yeah, by the way I agree with not trying to use the invert switch. I tried it, but every time I inverted my transmitter it made it harder to hold and I couldn't reach the switches very well.

I have a couple of switches I got from Radio South. They did not come with beauty rings. Let me know if you are interested.

When I broke a switch on my Airtronics radio I contacted Airtronics directly and they sent me a switch. Im sure its a common thing for them and you will have the factory switch. Just be prepaired to pay a little more. I think I paid about 15 dollars including shipping for a 2 position switch. Good luck

Actually Crowfly, you CAN get switches for Futaba radios from Horizon (Through Tower Hobbies). They have most of the switches for the Futaba series listed on the Tower Hobbies website, along with cross-reference information about which switch goes where in which radio.

Example Switch

Haven't found a supplier who lists JR switches online. You would need to check with a JR distributor or call Horizon. Electrically, you could substitue a Futaba switch. However, as you found they look a bit different.

Take cover
Its suprising how many people are prepared to bodge transmitters.

Give us a shout when you fly future3dmaster I will stay in the car

Unless you are an electronics expert you will struggle to find the correct switch, just because it looks the same doesnt mean it is the same.

They all have difference specifications.

And you would be surprised how many people actually know how to use a soldering iron and Ohmmeter. Figuring out what kind of switch you have isn't that difficult (only so many combinations you can get with three pin terminals).

I would agree that out of the general world population there are few who should be messing with electronics. However, many heli pilots are highly talented engineering-types who would have no trouble with a job as simple as replacement of a switch.
