I just want to make sure I am not missing something here. I have the original ignition switch that came with my circa '94 kit. Looks like a good quality switch so I used it. Wired it as per the Firewall forward instructions instructed. Engine starts and runs fine. I can turn off the ignition switches and the engine stops. Or.....I can simply turn off the keyed ignition switch and the engine stops, like a car.

Is this normal?

There are 2 Mag connectors on the back of the ignition switch that are wired in to the circuit, so electrically, I can see how it works but on other planes ( and my KF 4), a person can turn off the ignition switch and the engine continues running until the ignition toggle switches are turned off.
