Circuit for turning on a switch w/o a servo?

Anybody aware of a circuit online somewhere that would be plugged into a receiver as if it were a servo, and would complete a circuit when the stick is moved to one side? An added bonus would be to have two cicruits, one completed when the stick is on one side, and the other completed when the stick is on the other side.

This would be simple enough to set up with a servo that turns a switch (or two switches) on and off, but I'd rather have something smaller and simpler. I'm guessing it could be done with a single chip and perhaps a transistor or two. What model of chip can easily decode a servo signal with a minimum of external components?

Why? There's lots of possible uses, but the one I'm thinking of is a digital camera on a plane. I'd rather solder to the switches than use a servo to push them if I can -- it would save some weight, and be simpler to set up.

Jim Oddino's column in the latest issue of RCM reviews a switch just made available that should do the job. Don't have the issue in front of me, so can't give details. Also, George Steiner had an article, again in RCM, about converting an old servo to a switch. Sorry again for lack of details.

Have a look at this:

I found this link, and many others, on Alan's Hobby web site, which can be found here:

Good luck.

Doug,

I have used the circuit at the link below. It is drawn as a glow driver but other load devices could be in place of the glow plug.

Yup, that's what I was looking for. Thanks!

It's a bit more complicated than I was hoping for, but I can do that.

I just love ICs :)
