What key switch are you guys using with your 3300?

I used the ACS switch from Aircraft Spruce, but if I were doing it today I would just use toggle switches and a push-button.  They are lighter, available anywhere and cheaper.

I'm not flying my CH601XL yet but I second that suggestion. I went with an aircraft type key switch "Off, Right, Left, Both, Start" from ACS but if I were doing it again, I would use two toggle switches for the right and left mag and a start button. One obvious benefit is that when you are doing maintenance or daignostics, you can spin the engine with the starter while the mag switches are off. The key won't allow that.

Same here. The ACS switch does OK but is heavy and has some drawbacks.

The main drawback is that you can not run the starter engine for a few turns

 with the magneto's off.

I used a ASC switch also, but I bought the switch that is a off, left & right only model ,no start. I use a push button to start. This set up let me crank the engine with the mags off.

The security the switch gives is its best feature.You can easily wire from the master a second lead to a push button tied to the starter energize terminal.

I had  a Baron that didn't require a key but had a rotating key-like switch for the  mags and starter. Since it didn't require a key, in order to provide some  security there was a mic jack labelled COM3 inline with the starter. You had to  insert a mic plug that had its tip and ring shorted to provide a connection for  the starter. When you removed this plug the plane wouldn't start. Made it very  difficult to steal.

Thanks Craig, you have given me a good idea there. My key switch will of course provide the anti-theft protection since without it, the mags can't be turned on. I may use your shorted out 1/4" male mono plug as a more permanent way to activate the starter solenoid with the mags switched off. 



I didn't like the idea of a permanently installed second starter switch because of the likelihood of activating it accidently. The extra jack labeled "Starter" could not be activated without having the shorted out plug inserted. That's enough safety for me, and as I said, it doesn't have to be camouflaged with a misleading label for security in my case.



Thanks again for the idea,



Dred

I put the plug on a key chain that had the door keys on it so it was easy to

keep track of. It sure fooled the mechanics when I didn't leave the keys in

the airplane but instead handed them to them. I got more than one call (from

the same guy each time) telling me they had a problem they couldn't figure

out ... The plane wasn't starting no matter what they tried.
