Correct. The AV-master . . . when used . . . is part
of a bus feeder. It doesn't get 'protected'.

ANY toggle switch will carry that current. There
is no value to be secured by purchasing a 'military',
'aviation' or otherwise holy-watered switch.
Assuming that switch is situated in the ONLY source
of power to the bus . . . then why not power these
devices from the ENDURANCE bus which classically
enjoys two feeders?
The value of an 'avionics bus' was ill-conceived
from the get-go. Given modern application of DO-160 design
protocols . . . an avionics bus is totally unnecessary.
If you have dual, independent main busses with cross-feed
capability, then 'endurance' bus adds no value.

Thanks Bob for your time!!!

The only reason why I want an Avionics bus is to turn off unnecessary
electrical loads on the system during starting. I presume the Garmin
650
and the Dynon ADS-B and transponder are not susceptible to power surge
issues during engine start and since I will have two Optima batteries
this
is all way overkill.
The left bus is powered by the SD-20 and it has a Dynon SV-1000 with its
own
GPS and Dynon radio and the right side bus will be powered by a SD-60
and it
will power the Avionics bus with a Garmin 650 (radio and nav).
Here is the anointed military switch I am going with=85only $14.00.

Correct. The AV-master . . . when used . . . is part

The airplane will have two completely independent electrical systems
with
the ability to bus tie.
The pilot side bus will have a dynon SV1000 and Dynon radio.
The copilot's bus will also have a Dynon SV1000 and the copilot system
will
also power the Avionics bus that will power only a Garmin G650, Garmin
SL
15, Dynon transponder, and a Dynon ADS-B.
So I need to find a good quality toggle switch that has the capability
to
power only these five items and none of them use their complete power

I want to utilize a master switch like the Honeywell 2TL1-10A for the
Master/Alternator switch in the Z-14 DBDASB. I like it because it has
locking positions.
The data sheet switch contact description did not look like I expected it
to. Can someone PLEASE look at the data sheet below and tell me if it will
work for this application???
..
THANKS!!!

Yes, if I am interpreting the datasheet correctly, that switch will work.
Mount the switch with the keyway down.
Connect the alternator field to teminals 2 & 3.
Connect the master contactor to terminals 5 & 6.
As for the current rating, I do not understand it. But since the maximum current
under certain conditions is 20 amps, then most likely the switch will handle
5 amps at 12 vdc.
