A simple DPDT switch will do the trick: (view with a fixed font)I have a simple battery/electromagnet setup. Does anyone know how I
could set up a switch to reverse the polarity of the electromagnet?
(Besides switching the wires on the battery)

If you take a switch with 3 positions the middle position will turn the
magnet off
Now is there any kind of switch that will reverse the polarity of the"Jeroen" <jayjay.1974@xs4all.nl> wrote in message

I think this one will be better...

Now is there any kind of switch that will reverse the polarity of the
coil electrically like in this picture?

Once a current is applied to the red switch, it reverses the polarity
of the coil as long as the current is applied. If this sounds
ridiculous, don't blame me since I may have no idea what I'm talking
about.

Could you refer me to more specific information about a double pole,Now is there any kind of switch that will reverse the polarity of the

The "red switch" would be a double pole, double throw relay, with its
contacts wired as shown above (but you'd probably also want another
switch to turn the coil off...)
