Hi John,
That is definitely a relay. I can design a circuit with that that will allow the use of the
keyed switch.
That answers my question... This will allow a classic airplane keyed switch to be used.
Thanks for the help.

Jack,
See attached pic. I believe #5 is what cuts power to the EI when the mag switch is turned to the off position.

Jack,
The fancy electronics I referred to are not part of the EI, rather a separate component like a relay or something. Sorry I can't be more helpful.

Hi John,
This is the same that I have... I will have to look at the Rose EI schematic.
Maybe my problem is not a problem at all and it’s all in my head.... so many things running around
in there, and so few brain cells to handle them!!
Thanks
Jack

I have one Rose EI and the "mag" switch is wired identical to a regular mag switch. When I turn the switch off, fancy electronics that I don't understand cut power to the EI. Don't know if this will help.

Hi,
I am working on the final design of my electrical system and was wondering if anyone has used a standard
keyed ignition (OFF-Left-Right-BOTH) when set up with one mag and one electronic ignition system?
Up until today, I was thinking that I could use a standard aircraft keyed switch, but I didn’t realize that the mag is shut off by
grounding out one of the leads. This means that when the keyed switch is in the off position, the two terminals and the center
post are actually connected. And when in the BOTH position, the two terminals and the center post are not connected.
I can think of a way to use the keyed switch... but the motion of the key turns from right to left, not left to right. I would just need
to create a new label and use a relay for the Mag connection. This would have the added benefit of not having the mag wire
anywhere near the radios to cut down on e-noise. I just don’t like the opposite key rotation.
Are people with electronic ignitions using a two simple switches? 1) Elec-IGN 2) MAG
Do you have a key/lockset at all?
Any input would be helpful.
Thanks,
Jack
