Hello group ,Thanks for all the good advise I got  on the fuel system .I have started to assemble the beast and found that one of  my limit switches on my flap motor is broken .It is not a Zenith supplied item  ,I think it came of a Bonanza (courtesy of Dave Clay). Does anyone on the list  know of a source for these . Thanks

Heh, heh... those damned limit switches.   Seems they're not very rugged.  I searched the archives (Zenith list) and found someone discovered the ones Zenith supplied with flap actuators are no longer made, but there is a replacement unit.  They're also made by Honeywell, rated at 15 amps.  The replacement is actually a two-parter.  The microswitch and the roller/lever arm.  The switch is about $8 and change and the roller/lever is about $11 and change from www.gopherelectronics.com.  (There are a million part numbers for microswitches.)  The mounting holes are not of the same pattern as the old ones.  I don't have the part numbers handy but can get them for you in a couple days if you can't find the post in the archives.  The reason I ordered one is because I want to use two on the down-travel side.  If there is only one, and it fails, and the pilot relies on that switch to shut off the flap motor at full deflection, the flaperon bellcranks poke holes in the bottom skin, and you get who knows how many degrees of flaps--maybe enough to be catastrophic.  So I'm using two switches wired in series so if either one or both work, the circuit is opened.  On the up-travel end, there is a crow-bar terminal to stop any override in case of a failed microswitch.  (Speaking of the -801.)

There's probably lot's of switches available to do  this job, just has to be PBNC of adequate amperage. My comment is a big HERE  HERE  to using double switches in series! This is simple and avoids nasty  damage...
