No Alt or Avionics switches? If so, when do they get turned on?We have a standard ignition/start switch.
On the switch panel with all the lights, strobes, avionics etc, we have 2 switches for the P-Mags.
All our switches are switch breakers to avoid duplication btw.
Master on
Mixture rich
Fuel pump on - throttle advance to show fuel flow.
Fuel pump off - Leave mixture rich.
Throttle 1/4" open
Keep the start key turned until it starts......
Bingo every time when cold !
No master?Here is a pic of my planned arrangement.

The PMAG switches on the right are the momentary test switches.

Exactly as Carl on my RV-8/IO-360/AFP200/Dual Pmags:Both pMags on, prime (if cold) using the boost pump, then hit the start button. I use a toggle switch for each ignition and a starter push button - hate old school key ignition switches.

Exactly as Carl on my RV-8/IO-360/AFP200/Dual Pmags:
Master/Alt on
L and R Pmags on
Start button
Fly
When do avionics and fuel pump get turned on?
Since I have Space Shuttle switch guards, I pretend I'm Bob Crippen at every startup.... No sense in making a Shuttle launch out of simply starting an airplane.
I’m curious. It seems many have an alternator switch that they turn on after engine start. On all three of my RVs I just have an alternator breaker that is always on (as in I never open the alternator breaker unless I’m testing something).
So why do many turn on the alternator after engine start?

Seems like the mag on/off switches are redundant with the key switch. Why have both? And, I assume you have E-mags with self-powering internal alternators?

You want a switch for each p-mag to disable ship’s power to confirm the internal generator is operating.
I just pull the associated breaker to do this simple test from time to time.
