Posted: Tue Jun 09, 2009 1:25 pm Post subject: Canopy Switch

I want to add a canopy (open) warning switch to my Lanciar Legacy. I've

got a Dynon 180 which handles all the high tech stuff but I need the

appropriate switch and vendor information from which to source it.

Naturally the switch should be low profile or recessed and perhaps be

adjustable in depth such that it could be adjusted to the canopy

tightness. 



The premise of the Dynon is to alert via a contact light of a normally

closed or normally open item. Basically if it's grounded, it closes the

switch and allows the turns the light green. 



If you have completed such an installation I'd be glad to hear of what

switch you used and related frustrations if any.

Thanks in advance,

Glenn

Personally I would use a buzzer from Radio shack instead of a light so it works in bright sunlight.



Don't know if the Dynon will drive a buzzer or not but you might just avoid the Dynon altogether and run the buzzer through the switch.



I'm assuming here you want a warning that you left your master on?...if so you could wire the switch such the ground path goes thru the master switch.



If you just want a canopy open switch (not sure what value it really has?) then you can just wire a simple circuit thru the buzzer or light your choice.



Either way there is not much point in going through the Dynon.

Frank,

  

 Thanks for your ideas. No, actually I want what I asked for, a canopy alert light, not a "I forgot the master" warning light. The Dynon has some great contact display features that allow one to connect gear down, canopy open type things. When I'm ready to launch I'm looking strait at the EFIS and should see a big red light. You are correct, the sun can be a factor, but in PA where I live, rarely so. The probability of forgetting the canopy on a sunny day in PA is probably much less than forgetting it on an overcast day.

  

 The buzzer is a great idea, but does one really want the buzzer in your ears anytime the master is on and you are running around in sweat with the canopy in tilt position?

  

 I will stick to trying to find the right switch for mounting on the canopy jam.

  

  

 Glenn

Glenn, if you think the buzzer is a good idea but have the concern you mentioned, just install a second switch on the throttle. If the canopy is open and the throttle is opened more than enough for taxi….you get the idea.

Simple switches that can be either normally open or normally closed are

those that are used on housing security systems.  GE makes a line of

pressure operated switches like that, that fit into window frames.



An appropriate choice might depend on the area where you intend to mount

the switch, and the how small it needs to be.

The RV-10 guys have the same issue and can have a really bad day if they

launch without the doors being latched. I've got two friends with RV-10s

that have switches that are triggered by the door pins. I can't give you

part numbers but check the RV-10 sites. I think they are 3rd party and not

Van's.

Greg Young

I put a switch on the canopy latch of my RV-7.  It indicates that the  

canopy is "closed and latched."  I don't remember the part number of  

the switch but it was just a tiny little limit switch.  it has worked  

well for 180 hours.  Occasionally it even reminds me to close the  

canopy. 



There are a couple of pictures here...

Any switch that is a SPDT should work for what you want to do, I  

seriously doubt that the detection circuit carries more than a few  

milliamps.  You just need to find one that fits the geometry.

The mechanism referred to in RV-10s is a simple magnetic reed switch arrangement.  There is a magnet in each door pin and the reed switches mounted in the door frames.

Thanks to all for the suggestions. It sounds like the best solution is

to find a switch that fits the geometry of my latch and work it from

there (more fun there). I'm also checking on a pitot pressure switch or

throttle up switch as a backup.
