Electroair EA-15000 Ignition switch

[47U]

No.  Not compatible with the shower of sparks without an additional switch, which may complicate the specifics of the STC.

The Bendix switch in my M20C had 6500 hours plus when I sold the plane.

Not long ago I read about a fatal accident. The pilot turned the mags off and took the key out. A few moments later he turned the propeller slightly. The engine stared and ran for about two blades. It was enough to kill the pilot.

The FAA investigation found the ignition switch worn enough that the key could be removed without the mag being grounded.

This is a very scary, even if rare, possibility. It makes the dual switch set up attractive.

True, and I like the switches, but it’s pretty easy to leave them on after shutdown with the mixture.  You gotta assume the prop is always hot.  At least with the key you can check it during shutdown (cycle through off) and then remove the key.  However, I also like the look and function of the switches...

Do these switches work with shower of sparks?

Propably not without modification. The Shower of Sparks has an extra Pin on the Bendig switch which is activated either when you "push" before turning to starter or with some other models just when you turn the starter. The Shower of Spark connector is marked with "BO" (Booster Output). You can find it in the installation manual for the Bendix TCM Switch 10-357210-1.

 

This is a nice manual to the ignition switch.

You can find the different connection "modes" on page 11. So I guess you'd need a switch which can ground the shower of spark at a certain mode.

In the installation manual of the Ignition Panel, the shower of spark system is not mentioned and it seems like there is also not connector for it.
