The problem comes when the warning

I test the circuit before each flight.

My spoiler warning curcuit rigged between the landing
gear and spoilers on my
Jantar. The switch for the landing gear only opens
if the landing gear is down
and the button on the handle is fully up, indicating
a positive lock on the
landing gears. The switch on the spoilers only opens
when the spoilers are in
the fully locked position.

To test, I depress the button on the landing gear handle
and pop the spoilers a
little. This activates the gear warning by closing
both switches.

Just in case one of the switches fails during flight,
causing the alarm to go
off, I can deactive the system to avoid a beep-beep-beep
on a long flight. I
have a toggle switch mounted high on the panel to power
the circuit. Right
next to the switch is a large red LED. If I chose
to deactive the gear warning
system, the red LED goes on.
