Tip: New Annunciator Panel

Maybe so, Mike, but a NZ website search so far has turned up precisely 'zip'!! Unfortunately, with me working 7-days a week at the moment, I don't have the capacity to actually get out into the real world during business hours! If it isn't orderable (is that a word?) online it doesn't exist for me!

Cheers,

I'm having a very hard time finding a local source for them, or even anything like them. Closest I've got so far is one with an integrated pushbutton switch over thirteen times more expensive! If I had the make/model I could narrow my search. I'd order direct but they want a US $100 minimum order and a bank transfer. Ok, I could work my way up to the hundred bucks I guess with some other bits and pieces, but a bank transfer means a trip into town and another $25 for some lady behind the counter to press some buttons on her computer, which I absolutely have a hard time with...

That is, of course, assuming they would reply to my emails. Which they haven't. Which doesn't exactly instill me with confidence...

Anti- These things are not that expensive here. I could buy what you need and mail them to you if you don't need them yesterday.

Thanks Craig, and everyone else that has contacted me. Its great that there is such a cool bunch of people out there willing to help out. Us overseas lot, especially from lil 'ol NZ, sometimes find the logistics of getting bits and pieces something of a frustrating exercise, and usually a very expensive one. I reckon I'll have 30% of my plane tied up in freight and 'extra' stuff I didn't need but bought because it is easy to order lots than keep ordering littles!

Sorry to resurrect a dead threat. Paul I have a question on how you powered your ESS shunt annunciator.

I want to know when the switch is closed. That is, there is power via the E buss shunt. however, one cannot simply pull power off either side of the switch as there is always power on both sides of the switch UNLESS the master is off. That doesn't help me in the "left it on" scenario.

One though I had was that in normal switch open operations, the voltage on the ebuss battery side of the switch is about 1v higher than the main buss due to the diode, but when the switch is closed the voltage is the same as power is no longer flowing through the diode. this is independent of the position of the master

Is that what you did?

how did you make it work?

cheers

I know I'm not Paul (if I was I'd be smarter and better looking), but you could always simply use a DPDT switch instead of a SPDT switch. Wire your buses as you normally would to one side of the switch, and then wire power to an annunciator light through the other, independent side of the switch.

Doh!



Thanks!

Yup - DPDT - that's the answer!
