I'm sure you have seen this type before, it has the typical microswitch
located behind the latch.
I think it would be better if I also had a magnetic switch inline to also
verify that the canopy is shut, as the latch can be locked and the canopy
not captured. It is pretty obvious if that happens, but it would be a safer
installation.

Subject: Canopy Latched Sensor
I'm looking for a better way to implement the canopy unlatched warning
system on a Long-EZ. The standard method is to use a small microswitch
that responds to "canopy latched". (This is not the same as "canopy
closed", which would be easy enough to implement but I want a "latched"
indication.)
Here's an illustration of the standard system:
http://users.lewiston.com/hth/jd/CanopyLockMicroswitch.jpg
When the canopy locking handle is pushed forward (left in the image) far
enough to latch the canopy locking mechanism, the head of the screw on
the handle (at the right in the image) fits in the hole on the latch and
actives the microswitch through its (specially bent) lever.
I'm not happy with the microswitch as it doesn't hold up well under use
and wonder if any Aeroelectric Connection readers can come up with a
better idea. I've searched for optical interrupters but can't find one
with a gap large enough for the head of the relatively large #10 screw.
I'm not familiar with any specific reflective-type optical sensors but
I'm guessing that would be the way to go.
Any ideas?
Thanks,
Joe
