Rowland,
Glad to hear your upgrading your panel. Been there, done that. Try to
keep the plane young!
The trim indicator and trim switch dimensions are on the Ray Allen
website in the instructions.
I=99ve attached the .pdf from my wiring installation files. It is
a bit dated but they haven=99t changed in years.
Note: The indicator and switch are disgusting to wire due to the small
#26 gauge wire and the dumb fact they are surface mounted and use #2-56
screws to hold them.
Consider the following:
Buy the appropriate D sub pins and crimper for these angel hair wires to
make removal and replacement easier or I solder the wires to a pcb pin
connector (shown in attached .jpeg) for the switch and indicator and
mount the trim switch and indicator plugs on a board but you can let
them hang free. I Wire the board to the airframe using about a #20 to
22 wire to the panel to airframe plug because I am annul. but I can
slide out my transponder to get quick access to the board for
unplugging.
Also, I redux a tapped strip of .032-.040 aluminum as my nutplate so I
never have to try to get a tiny nut off the back of a hair like screw.
Life is too short and my eyes and patience are not what they used to be.
To service a bad indicator or switch, simply unscrew the switch, pull
the wire forward, disconnect the pcb connector. Remove the pcb
connector from the bad indicator/switch and solder on to the new one.
Plug it up, screw it back together and leave in less than one hour.
There are too many types of circuit breakers. Are you using Klixon or
some other manufacturer? What I=99m wondering, is how you mount
your breakers. I put the breakers hard against one another so they
can=99t rotate, and I fabricate a bus bar with even holes to screw
the breakers to which makes for a very rigid CB panel that is very
compact. In 12 AY I have three different brands of CBs of all different
lengths and it makes life difficult to get even spacing.
Regards,
Bud Yerly

I will be modifying my avionics panel and would like to prepare the
new one prior to stripping out the old one.
I intend reusing the trim switch, it's position indicator and the
square type circuit breakers.
Does anyone know what the hole cutout sizes are for these items?
John - here attached is a screenshot of a small part of my radio panel
drawing with dimensions (in mm) added. An export from this drawing was
used to water-jet cut the panel, and the switches fitted pretty well -
see:

However, it appears you have the meter-type indicator rather than the
LED bar that came with my kit, so the hole size for that could be
different.
