I'm interested in switch. Doesn't it need 2 terminals, one to mag and one to ground. How does this one work? On should go to mag and off to ground.

The terminal on the switch connects to the magneto. That terminal is grounded to the shell of the switch when in the OFF position to ground and kill a high tension magneto. If the shell is bolted to a grounded metal panel then a ground wire is not needed. It the switch is mounted to a wooden panel or otherwise ungrounded then a ground wire from the shell to the car frame or other ground will be needed.
