I have a related question:

Why did LEGO add a permanent post to the new switch? The old polarity switch could turn 360 degrees if you didn’t add a post, but the new one only turns as far as its built-in post allows.

I will grant that I’ve never actually needed to turn the old switches 360 degrees, but the option was at least there.

I’ve gotta agree with that question: I loved the fact that the old one can turn 360 degrees and have used that option to make it do some fun and screwy things.

You guys got to try this:

Get one of the RC Racer units. You know how the steering motor only turns a little to the left and right with the remote?

Well, connect a small axle to the steering motor and the polarity reverser. Like this:

Connect a battery box to one end and a motor on the other end. When you flip the toggle on the remote the steering motor turns and activates the motor connected to the pole reverser.

The RC unit steering motor has a spring loaded “center return” so when you let go of the toggle on the remote, the pole reverser returns back to nuetral or an off position.

It’s really cool! I guess it is called a mechanical multiplexor? Is that the proper name? Or is it just a mechanical remote of some kind? Either way, it is a way to get a third motor control from the RC Units. CAUTION DO NOT use with Racer Motors!
