Has anyone done this mod recently?

Doubling the Functionality of the KeyChain Remote

If so, where did you buy the switches from?

I searched GOOGLE for the switches several months ago (and again a couple of weeks ago when I posted this [to-date UNANSWERED! :eek:] question on another Forum :( ) and I either find unit prices of $2.50 - $3.50 with $9.50 shipping (OUCH!), or unit prices of $0.50 - $0.70 with a $20.00 minimum order. Also, these sites that I've found so far don't list the size (DUH!)

I'd like to mod ~4 KeyChain Remotes (and maybe some PalmPads) and spend a "few" bucks. If others are interested (~36 more switches), we can do a Group Purchase for 40 @ $0.50 each. :)
 
Thanks electron, but I like my PRICES and SHIPPING (one of your LINKs was in Australia!) better:

Electronix Express - Tilt Switch - Mercury :)

Anybody interesting in buying the remaining ~36???

BTW, thanks for your FROOGLE example. I use GOOGLE/Web and DEJANEWS/Groups all the time and previously thought of FROOGLE as just another PRICEGRABBER - but, the pictures are a nice touch!

I know! :(

I currently use my (almost *FREE* during SALES) PalmPads to directly control devices and my KeyChain Remotes to execute MACROs. The ability to DOUBLE the number of MACROs from 4 to 8 is certainly appealing (for $.50!).
 
digikey.com has them as well, if I remember correctly, shipping is around 5 bucks, and there was a minimum of 20 units.
 
I think some older style thermostats use a type of "tilt" switch described in that mod. You could always just use a small slide switch or something like that (a small pushbutton maybe) since its just a contact closure. The disadvantage though would be you would have to push or slide a switch before you pressed the X-10 button.

Be aware that mercury is a known health hazard and systems are getting away from using anything mercury related (as THIS link suggests.)

Yeah, but it's *WAY* too BIG! The switch in the mod fits BETWEEN the two AAA batteries!!! :eek:

But, *NOTHING* is as small or convenient as the Micro Mercury Switch... :)

Who knows - maybe in the course of the next few days, several other Members will become interested and I can just drive on over to Electronix Express and pick up $20 worth (they weren't interested in selling me 4 last time I called... :( )

I'd avoid doing anything with mercury switches. It's just not worth the risk. You can do the same thing by wiring a small switch of some other sort in there - you just lose the tilt operation. There are ball/wire-based tilt switches out there, too.

Several schools have been shut down recently due to mercury contamination (spilled mercury).

I remember as a kid what fun it was to take some mercury and roll it around in the palm of your hand!

I also remember the massive headaches I invariably got about an hour fterward. I finally put the two together after several years. I won't claim to be the sharpest tool in the box

I fly a RANS S-12 - originally setup as an ultralight trainer. I'm building a RANS S-6 which will have a Jabiru engine. I don't have a completion time yet.

Bruce, that piper sounds WAY nice. Maybe I'll change my build plans for the next one! Yeah, I get just about as much kick out of building them as flying them.
