servo winch on a 3 way switch??

[draper_88]

I have built a servo winch using the tech on this site but i was wondering if it is at all posible to put it on a 3 way toggle switch? I am wanting to put it on my trailer and I only have a 2 position switch on my radio so i thought instead of trying to get it to work with my radio i could just install a 3 way togle on it but i have no idea if it will work or not. Any help or suggestions would be greatly appreciated. I am not against hooking it to the radio if anyone has an idea on how to do it without buying a new radio. My radio is a dx3s. Thanks for any help.

a 3way toggle should work fine on a servo winch just get the switch and power should go to the center and hook the servo motor wires to it but never tried it. it shouldnt be to hard

Yeah, it will work directly from a 3 position switch. You have to ditch the circuit board in the servo and hook the switch directly to the motor in the servo. You will need a DPDT (double pole double throw) switch for it to work right. Here is a drawing showing how to hook it up:

so I should be able to just wire the motor up to the switch then. and then i wont need the signal wire or board then right? thanks for the help guys I will have to go to Radio Shack and get a switch now and try it out.

You got it. Save the signal board, you might find a use for it later.

Just make sure you get a DPDT ON-OFF-ON switch. Radio Shack should have what you need.

edit: looks like this is what you want from Radio Shack:

So how does it work if you use a 3 pin switch? Like i have, i need to do the exact same thing, thanks

A 3 pin switch is NOT necessarily a 3 position switch.
A 3 position switch does NOT feed power to either pole when "centered" (off).

To wire it, power/signal goes to the middle pole (usually.....read the wiring diagrams or check with a meter), the "switched" power goes to either switched pole.

it doesn't no way to run the ground correctly

My bad....too many work hours this weekend on top of a "regular" work week.

Yes, you need a DP switch to "swap" the power polarity to the motor.

My bad to anyone following me.

If the pins you are talking about are the switch contacts, you need a switch with six pins on it. As was mentioned earlier, you want a Double Pole, Double Throw, Center Off switch

I like the idea of using a toggle switch for this.
You can get a Double Pole, Double Throw, Center Off toggle switch that has a spring return to center. This might be good because if the switch gets bumped, the spring will push it back to the off position for you.

If you really want to operate it from your transmitter with a two position third channel, I make a replacement winch controller that will work for you.

i'd have to see it mapped out

Too many hours working this weekend.......sigh.....

[muddawg]

what i don't understand is if the ground from the motor and battery are tied together and you are using the switch to move the positive from one side to the other off would work and forward would work but reveres would have positive and ground going to the same side of the motor causing a dead short unless i'm just missing something

Touche.......my bad.

You are correct, I was not taking into account the motor reversal (edited my 2 previous posts, than you for pointing this out.).

Yes, you need a double pole switch so you can swap the polarity of the DC power to allow motor reversal.

Time for some ZZZZZ's for me......

no problem i was actually hoping that i was just missing something
