Well, you're good at ebay :) That last switch look like one of those that requires considerable force to switch - mostly to be safe. I am just guessing. but it would probably be too hard for a little servo. If you like the servo idea then get two simply micro switches and do some mechanical arrangement. It is a bit Goldberg like, so the relay is still simpler. I think those relay modules are OK.


Yes, love eBay  :) Even if just to get an idea of what's out there.  I have some high-speed metal gear servos that might work...I guess we'll find out. What I'll probably do is try to mock up the relay method first...it would be nice to keep everything as electronically based as possible.

Could you post a picture of the label on the motor or copy the information on it over here ?

These actuators sometimes have an "encoder" wheel, that sends a pulse per rotation of the motor or its wormwheel driving the shaft.
If this one does not have that, you might be able to build it in yourself.
This would probably be better than to use a potmeter.


Hi MAS3, to my knowledge there's nothing giving position feedback from this actuator...but I may be wrong. There are only two +/- wires coming from the unit.

I'd be open to seeing what's inside it - any idea what the encoder wheel part looks like?

It was a custom built actuator that I got in a clearance sale. Here is a close up of the label on it:

Here's a really nice 3 position rotary switch that can be hooked up directly to the servo - cool!

There is info below on how to use a radio shack rotary switch for reversing a motor via a servo.
