Change rotation of a 12V motor back and forth

I have a 12V electric motor from a treadmill that I want to be able to change back and forth from cw to ccw. Any suggestions on switches and wiring would be appreciated.

Welcome to the forums.

Depending on the load.... it can definitely be done with relays.
Possibly a switch.
Is there an amperage draw for that motor ?

If the load was under 15A or so.... you could use a HD toggle switch....

It can be done with DPDT switches with center off. Just wire center terminals to the motor and one side of terminals to 12V + and -. The other terminals with opposing polarities.

You can make one with a 4 way switch as well, but then you will need another switch for on/off.

Make sure the motor comes to complete stop before switching the direction. Otherwise it will fry the motor or the wiring.

Thanks for the advice. I picked up a Grote 15A 3 position switch at a local auto parts store. When I got home and opened the package it says "15A 125VAC / 10A 250VAC/ On Off On" but nothing about 12 V application. Does it matter if I use this switch in a 12V application. I live 40 Km from town so I'm not real anxious to go back if it isn't necessary.

The voltage rating of a switch is the maximum voltage it can be used on.
That should be fine..... give it a try.
