Has anyone designed an electric ladder diagram to toggle, alternate, two (2) electric AC motors. This is using the NC and NO contacts of a couple of contactors ?. Appreciate your help.

What activates them?

A switch?

Each time on, the other runs?

That's an alternator!
Best bet is to buy a socketed device. Made just for that. It looks like a cube relay.

Other option is a ratchet relay.
