Am I missing something here? If you have a door warning circuit that
brings a red light on when the door is open why do you need a test
circuit?
Standard check on ground-
Door open, red light on
Door closed, red light out
Surely you have just done a light test ?

Tony,
Just make sure you have a push to test as "no light" doesn't tell the
whole story. It's just test cirucuit and extra wire. I can build a
door in the time it would take to lead you through how to do it fail
safe with proper door plunger switches that are adjustable.
I just saw something the other day. A strap of line attached to the
door handle so his wife could pull the door down. It was a lovely
decorative line, worthy of any draperies. Too bad it catches your hand
anytime you reach your hand forward or aft. I guess his wife does not
touch the controls or move when she is in the plane. He had no door
guards either.
I'll just push on the door in the center after closing. If you push
firmly, you will assure a latched door or see it move.
Regards,
Bud

Hi Max,
Rather than 2 green door lights continually on, my intention is to have
a single circuit through both shoot bolt switches, and if either isn't
closed, the door and the circuit, a red light stays on, or inflight
comes on. That way, my panel has no lights unless something is wrong.

And then install a test button to verify that the leds are still alive.
Complicate cabling AND checklist.
With thanks to Raimo Toivio for the design and components, I have
mounted two robust pressure switches which will give me two lit green
LEDs on the panel when the rear shoot bolts for the two doors are
engagedno need for test button to ensure system is

tabs on both doors which are located so that pilot can reach to ensure
