    --> AeroElectric-List message posted by: "hausding, sid" <sidh@charter.net> Could you send the link please? Sid ----------------------------- You guys have probably already seen this: It's a version of the common plug-in plastic fuse. An internal LED glows to indicate a blown fuse. Auto Zone.

    Subject: Keeping flash tubes nice
    --> AeroElectric-List message posted by: "Lawson, Michael" <mikel@SSD.FSI.com> I am in the process of wiring my (Whelen) strobes up, and I noticed how nice and clear they look when new. Last time I walked around Oshkosh, I noticed that many flash tubes on experimentals seem to have a darkened, brownish look, almost like they've been overheated. Is this indeed caused by overheating, by having the tube enclosed behind a plexi lens and not exposed to the air stream for cooling, or is it just a natural degradation of the flash tube over time? I checked the archives, but couldn't find anything relevant (there are LOTS of messages about strobes to wade through). Any suggestions on keeping flash tubes nice and clear?

    Subject: Favorite "switch feel"?
    --> AeroElectric-List message posted by: "Lawson, Michael" <mikel@SSD.FSI.com> Does anyone have a favorite brand of switch that they prefer to use, based on its tactile feel and smoothness of switch action? Once you get beyond the parameters of AC vs. DC ratings, rated actuations, and whatnot, there still seems to be a noticeable difference in the operation mechanism of different switches. In my job, I am lucky enough to get to flip switches for all sorts of aircraft in Level D simulators. I was flipping a switch from a Falcon 20 the other day which made me say, "Wow -- that's a REALLY nice switch action! I'd like to have that switch in my RV." Unfortunately, it's made by ECE, a French company ("L'Equipement et la Construction Electrique SA"), and I don't have any ordering information. (The specific switch in question was provided directly by the Falcon factory for this simulator, so I have no way to order one on my own.) Now, there are those who will say, "Don't worry about it, just forge ahead with whatever switches you can find that are adequately rated." But, to me, small details like the feel of switch actions are one of the things that just make me feel good (and proud) of my airplane. Okay, your favorites?

If there were switches that felt like the shutter button of a Leica M3, I'd buy them. Hewlett Packard thought switch "feel" in calculators was incredibly important; they provide important tactile feedback. Same with IBM. No matter what computer I use I take my own IBM/AT keyboard to use. I once complained to a switch manufacturer that a potentiometer felt "cheap" and was told by the manufacturer that they can make it feel any way at all by changing the silicone grease. So I ordered per their suggestion XYZ grease and everyone was happy. High-priced audio equipment makers specialize in this art. But I suspect that most corporate bean-counters are not interested in this, and many manufacturers just stumble across it accidentally. Everything feels good in a glob of grease. Regards, Eric M.

Sometimes the potted electronics must be repairable. Sometimes great thermal conductivity is needed. Sometimes it must be clear, sometimes colored. Sometimes very viscous, sometimes not. Sometimes flexible, sometimes like ceramic. You can use regular epoxy or urethane if the job has no particular requirements. Silicones sometimes eat up fine PCB traces unless you get electronic grade. Just coating the circuit with clear epoxy has its "adherents". (I am so easily amused...) Like everything else---just Google it. Loctite and 3M make lots of the stuff. Regards, Eric M.

    Subject: Re: RE: Favorite "switch feel"?
    --> AeroElectric-List message posted by: Dave Morris <dave@davemorris.com> I can relate to the need for good switch feel. I hate clunky switches that are too hard to flip. But gadzooks Eric, I absolutely hated the IBM keyboards, so I don't know what the HECK you're talking about! LOL! Anyway, I was in Altex, an electronics store in Dallas today and flipped all the switches they had on a display board there. Didn't really like any of them. The metal ones are usually too "hard", and the ones with plastic bat handles are usually too "soft" and easy to accidentally flip. I did luck out with the switch panels I had built by Aircraft Simulators (www.AircraftSimulators.com), because they feel "just right". They are made by "Chili" and rated at 10A.

    Subject: Re: RE: Favorite "switch feel"?
    --> AeroElectric-List message posted by: Jerzy Krasinski <krasinski@direcway.com> All of that reminds me a discussion I once read in a gun journal. Someone discussed parameters of several guns, and in addition to usual parameters like weight, caliber, velocity of projectile, etc. he included also the "feel" - whatever that means, because he never defined that parameter. Strange thing, the most expensive guns scored the highest in that "feel" competition. I guess, it feels good to have something expensive (Hewlet Packard?) or rare (French?). A switch made of unobtainium probably would beat anything else in that competition.
