So do I have a 7amp switch or a 30 amp swithch if used in my 14vdc airplane.<< You have a 15 amp switch! In fact, it is also a 14 amp or a 13 amp or a 5 amp or a 1 amp switch at anything less than 250 volts. The ratings listed on a switch are the MAXIMUM use for that unit. If you want to use a smaller voltage, fine...it is still capable of handling 15 amps. You would want to use a smaller rated switch if you wanted to save money or weight or size. A similar example is fuses. Say that a fuse for your auto or aircraft is rated for 15 amps and 32 volts. Just because you use it on a 28 volts system, or a 14 volt system doesn't change it's amperage rating. It'll still trip at or about 15 amps. It's been awhile since I taught electronics, but there is a bit more to it all than that. But basically you won't run into any trouble if you treat the ratings on switches as MAXIMUMS, not REQUIRED.

Keep in mind that switch ratings are based on electrical and mechanical stresses over tens of thousands of cycles. Further, the ratings speak to currents that the switch must make and break along with the nature of the load's dynamic responses (resistive, inductive, lamp loads, etc). The catalog ratings are strongly influenced by environmental and utilization numbers. I've often observed that more switches in small aircraft die for LACK OF USE than for OVERSTRESSED USE. Generally speaking, ANY full sized toggle switch you pick up with a rating of 7A or more at any AC voltage will probably run the lifetime of your airplane in ANY location in the system up to and including boss-hog pitot heaters with 30A inrush and 10A running currents as long as they're regularly called upon to switch those loads. I.e, cycle every switch, every flight cycle. 10 years from now at one flight/day your switches will have less than 4,000 cycles on them. If your e-bus is wired per a Z-figure, it has TWO independent power pathways (a design goal). So failure of any one pathway does not generate an 'emergency'. If the AeroElectric Connection has any agenda, it's to plant and nurture the seeds of an idea: "No single failure of any component should be more than a maintenance event." This includes ANY switch on the panel. I'll suggest the concerns you cited above are overblown. The reason one might consider adding the relay at the battery bus for larger e-bus loads (greater than 5A) . . . http://www.aeroelectric.com/Pictures/Schematics/E-BusFatFeed.gif . . . is to create a mini-battery contactor AT THE BATTERY bus to account for the fact that the always hot feeder is protected at greater than 5A. Such feeders are worthy of disconnection AT THE BUS instead of running the wire all the way to the panel. This is a crash safety convention borrowed from the TC aircraft world and has nothing to do with the RATINGS of the switch. One could run a 15A e-bus alternate feed through a 7A rated toggle switch with very little concern for service life and zero concern for failure.

I stated: "The only down side is that 3-4 foot length of 2-4 AWG is hot all the time the master is on". If the master is off before impact it's a moot point, but light airplanes are notoriously not cash worthy. The steel tube frame is best, aluminum semi- monoquoque structure is OK, but as a RV builder the fuselage is not that robust. However the beauty of the RV is integral wing tanks outside the cockpit and slow stall. Fiberglass / composites, are one of the worst. It does not deform or yield to absorb energy. It strains and than ruptures like an egg. As far as fire any plane that has fuel in the cockpit is at risk of being a future weenie roast. >Dave Morris WROTE: > >This happened to a friend of mine who would have walked away from a >crash if it had not been for that one little spark. Your comments about skin graph are quite graphic. Sorry to hear about your friend but I don't think the fat starter cable would have made a difference. He had fuel and a spark, what would another spark have mattered. Besides as Bob, sportav8 pointed out, the master relay will eliminate the issue all together if you turn it off, but it does not matter, if you are comfortable with the FW contactor than put one on. I am just no convinced it will eliminate the chance of fire significantly. If you look at firewalls of RV's with big bare copper straps and fuse blocks all cluster just a foot or so away from the gascolator does not give me warm fuzziness. I guess the best defense is practice you emergency forced landing procedures and remember to turn the fuel and electrics off before the ground smite ye mightily. >What's a few bucks, guys?

I would suggest the heavy duty integral fire sleeve (brown) fuel lines from StratoFlex or Aeroequip. I don't think Earls' has that? Also an aerospace quality hose, if you are worried about fuel leaks and fire, should be made by an approved shop. It cost a lot more than Earl's, and as you say what's a few extra dollars. Also Nomex and helmets and gloves are all good stuff. Bird strikes are deadly in fast homebuilts with thin plexiglass windows. The window on the 757 I fly has multi-panes and very thick. The 250 kts limit below 10,000 feet is in part for bird strike. I had one and it shattered the windscreen. It happened at 9,000 feet! It held. So I expect to see you with a helmet and eye protection and a nomex flight suite going fast Dave.

It holds my mic and earspeakers; 2. it provides protection for my noggin from the canopy when someone else is in the airplane yankin'-'n'-bankin'; 3. it provides much better passive hearing protection than a headset; 4. it keeps the sun off my head; 5. it keeps my head warm in winter; 6. the visor provides sun and impact protection for my eyes without interfering with my peripheral vision; 7. it provides an attach point for an oxygen mask (those of you building a Harmon Rocket might consider this as your Rocket will work just fine up at the flight levels where you will get really great fuel efficiency); 8. you can paint stuff on it to look really cool or really stupid depending on who's looking. -- Brian Lloyd 2243 Cattle Dr. brian-yak at lloyd dot com Folsom, CA 95630 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . . - Antoine de Saint-Exupery ________________________________ Message 9 _____________________________________ Time: 11:06:31 AM PST US From: Mickey Coggins Subject: Re: AeroElectric-List: helmet (was: Why use starter contactor (fire)) --> AeroElectric-List message posted by: Mickey Coggins Brian Lloyd wrote: > 8. you can paint stuff on it to look really cool or really stupid > depending on who's looking.

If visor is down in front of you, then a piece of soft leather or similar on top of helmet protects canopy. . . . If visor is up, then it will contact canopy - so, one might want to put a bit (1 foot square or diameter) of "cling plastic" on canopy above where your head will be. Lots of folks already have sun barriers above them, which would protect the plexi. Brian, my helmet simply has a snap on each side for attaching the elastic strap on the visor. I can unsnap the clear and snap on the colored visor when needed. I use the clear most of the time, for bird protection, with sunglasses underneath when needed, so don't really need the tinted visor. In combat in 1967 up "north" in Package 6, one day I told myself the visor was bulletproof - I no longer suffered anxiety rolling in on a heavily defended tgt. Prior to that I worried a bit about a 37 or 57mm in the face. Piece of cake after I put on my bullet proof visor. Now the biggest threat is buzzards, snow geese, and other large "mm" birds. Visor is real protection in event of a birdstrike, not just make believe. I just had 3M tinted window film (thin sheet of plastic) on my windows on the Gulf Coast last summer - makes the windows rather "hurricane proof". The website tells of a company putting these films on windows of a mobile home "office" at some petro-chemical plant construction site - 3 days or so later, there was a big explosion - trailer was blown over on its side but windows were intact. . . . I'm going to consider experimenting with that stuff on the front part of my RV-6 tip-up canopy for bird resistance. Hey, we are on the "Lectric list" - Sorry for being "off topic".

I can attest to them working, I took a bird right in the face, or in line with my face, didn't hurt a bit, the bird wasn't in very good shape though. A squadron mate of mine took one in the face on a low level Nav in an F-18, he was so incapacitated that he crashed with no attempted ejection. I'm with you on the visor thing, there is no better sunscreen and glare removal. For those considering a helmet, Flight suits offers active noise canceling for your helmet. I personally would rather have thousand dollars in a helmet than a thousand in a set of Bose.
