How about just Installing some MOV's and or Protection Diodes. Or even an Isolation Transformer or a Triac o Solidstate Relay.

Is there a Timing or a Pulse Width Modulator circuit to turn the Coils on and off? I personally don't like MOSFET because it is static sensitive. You have 2 coils attached to a Static Sensitive Device. These coils cause Reverse Spikes as the Fields colapse. Also EMF Waves. I just don't like the Idea. How about a Electronic Ignition type Circuit Instead using Discrete Transistors like a 2N3055.

Does the class have a Computer? You could use it as a Central console. If each has a Computer you are in Business. Voice Recorder Program built in.

Here is steven's Picture Modified so you can see it.

The new Name they use is TILT Switch . They now make them without Mercury. Mouser Has them and They can ship worldwide. Type in Tilt Switch in the Parts Search. http://www.mouser.com/index.cfm?handler=data.getPcodes&pcode=Mountain%2BSwitch%2BTilt%2BSwitches&pcodenumber=01014

Try This.

Draw a picture. I think the problem is the Direct TV hooked into the system wrong. Give me more on the switch.

hotwaterwizard replied to Marco's topic in Datasheet/Parts requests
what model printer did they come out of? Maybe we can find a service manual or Schematic for it and get the info that way. -
WOW that is alot of Datasheets! Try some of the sites in this post.http://www.electronics-lab.com/forum/index.php?board=12;action=display;threadid=625

Bill of material for CD - Boombox
hotwaterwizard replied to Suren's topic in Datasheet/Parts requests
2.3 megabites is almost 1000 times too large. That is too bad too. I have Datasheets Larger than this and I can not share them with the Members. Limitations should be removed for some sections like Datasheets and Service Manuals sections. I couldn't Share this even if it was a Request from President Bush. -
Here is one very simular. http://www.electro-tech-online.com/
