First thing I'd like to know how the igintion / starter buttons work.
#1 - ignition off : it is a spring loaded button or a 2-way switch?
#2 - magnetos 1+2 on : I believe it is a 2-way switch, pushed in for
magnetos ON, push again magnetos OFF
#3 + 4 : magneto 1 or 2 OFF : testing the magnetos. It is a spring
loaded button ? For spring loaded I mean the pilot has to hold it pushed
for switch off the magnetos while checking it
