Cool button.

I'm using a regular key switch for mags, push-button start on the infinity grips. (taildragger)

(and one mag is is not a mag: LSE-Direct crank, which has option for keyswitch control)

I believe we have found a new "Hot Button" topic (pun intended). 4 pages and growing.

I have a momentary toggle. I might consider a DPDT toggle for the plasma and tie it in with the starter solenoid. (starter toggle is not active unless the plasma is hot)

spitfire starter button
 
I found a starter button of the type used on the Spitefire. I cannot figure out where to install it on my 8A.

Any suggestions?

You never want the non impulse mag to be hot when you engage the starter. In fact, it should be wired to not allow the starter button to engage without the advanced mag grounded.

You are right. I had that backwards and went back to edit it but not before I had been quoted. Oh well. I stand corrected.

I WANT ONE. I would proudly display that sucker on my panel.

Any issues with kill switches and electronic ignition?
 
I have a push button starter in the -6 I bought flying, and during my recent panel upgrade, I placed a kill-switch (as described in a couple posts in this thread) in line between the mag and the Lightspeed switches and their components. With the kill switch off, the starter will turn the prop, but the mag and LSI are disabled, so no start can occur. Seems to work, but...

Now when I run-up the engine, if I turn off the mag switch (and run off only the LSI) I get a 100-110 RPM drop, and the motor runs noticibly rougher (it used to drop maybe 20 RPM and ran fine during run-ups with the mag off before the new switch was added). Drop is normal and engine runs fine when I turn off the LSI.

An RV friend just told me he saw a post that described problems with adding extra switchology to electronic ignitions or P-Mags, but a search has come up empty for me. Has anyone had similar problems or can anyone point me to possible solutions? I've checked for vacuum line leaks and wiring issues, checked all the plugs (which are new), and can't seem to find a reason for the rough running. Any help would be appreciated!

Thanks, and Cheers,
Bob

PS: That Spitfire starter button is very cool, as are the others shown! Mine is a very basic red button

Master security
 
The master on an Ercoupe is behind the pilot's shoulder. On a tri-pacer it's under the seat. Even experienced pilots (not familiar with the make and model) will sit there for an hour trying to figure out how to crank it. No better security than not being able to turn on the power until sombody shows you how!

Spruce has
 
a shrouded red push button switch that I used for my starter. I wired it through a hidden toggle for security. Haven't run it yet, but it should hold up OK with the diode across the starter solenoid. For the mags, I used two locking toggles (no lock really, just need to pull out before actuating). I like this setup because you have no single point of failure for both mags (like the standard keyed switch).

For higher security than the hangar, I will use a throttle (or mixture) knob lock.

Did anyone mention using a keyed on-off master switch? Start button doesn't work if the master is off and the key is in your pocket.

The new bird has a canopy lock because I once walked up to my airplane at dawn-thirty to find a certain jerk aviation editor taking pictures. He had removed the cockpit cover and all the loose contents; they were piled in the wet grass, and dew from the upper wing was dripping on the leather seat. Point is, it ain't just Bubbas who take liberties, so do figure in some switch protection.

No, I didn't hit him, but I should have.

I will be putting a lock on the canopy. If I catch anybody trying to get in my airplane for any reason... well lets say he will have a sore rump. Here is my setup, the button is the one from B&C.
