Minimum Panel question

[Maverick]

I am working on my panel and I am wondering how many switches one needs. It's been too long since my last Kitfox to remember what I did before on it. Here is what I have so far:
Steam gauges for AS, Alt, VSI, compass, and turn and bank.
Grand Rapids EIS
Garmin 200 Com
Garmin 327 Txp
Garmin 660 GPS
uAvionics ADSB
Whellen strobe and marker lights

I am using fuses and have two buses of six fuse slots each. My plan is to have one buss for avionics/EIS and Turn and Bank and the 2nd one for lights and trim. I have a main master switch for the engine and separate one for the avionics buss. I am thinking that the main master could also power up the non-avionics buss. My question is whether or not this is good practice or whether I should also have a separate master for the second buss. Since I have switches for the strobe, nav-lights, and trim, I think maybe I don't need another switch/hole in the dash.

I'd like to hear others opinion on this before I move on to something else.

Thanks,
Maverick

One needs two more switches then they have. I put in two extra switches that were labeled AUX that were hooked up to nothing. By the time I flew I had stuff on those switches. I think the ability to load shed is important. My plane switch are:

Master
Essential Buss(for running only the engine, EFI etc)
Fuel Pump A
Fuel Pump B
Alternator 18A
Alternator 40A

EFIS
COMM
NAV/STROBE 3 pos
Landing Light, recognition 3 pos
Heat HI LO 3 pos
Panel light, cabin light 3 pos
AUX1 USB charger on or off)
AUX2 (runs A/F sensor, long story why this needs to be switched)

Maverick - right now I'm at 13 and one is still listed as a spare. Here's a cut and paste from the spread sheet I'm using. It is not yet complete - I'm still double checking the current draws and fuse requirements.
