This same switch will also remind one to turn off the low boost as you descend again past 10,000. It needs to be a SPDT. I'm planning on lighting a simple enunciator bulb on the panel. It will come on at 10,000 feet and extinguish as the Low boost is turned on. The reverse will occur on the way down. I've found such a critter and am trying to get a sample order going but I suspect they'll want some exorbitant price unless there is a quantity of switches to make it worth their while. Assuming that with a quantity order the price would be reasonable (???) is anyone interested in joining in? Possibly someone also knows of a ready "off the shelf" source of this switch? Another possibility for one of you "EE" types out there that a simple circuit could grab the altitude encoder output and look for altitude above 10000 feet. Any ideas or interest?
