Fri Aug 05, 2005 3:54 pm tom Guest You can do this by hooking the switches up to a microcontroller such as a PIC from www.microchip.com. Connect one side of each switch to ground and connect the other side to both a 10k ohm resistor and an I/O on the microcontroller. The other side of the 10k would go to the supply that is powering the microcontroller. You would then have to write firmware for the microcontroller to set what the switches would do and what their priority would be. Good luck. The following kit may give you a good start... http://www.designnotes.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=K8048&Category_Code= We also have a version that is already assembled.

It might not hurt to check out their website. www.qprox.com really cool stuff, and no moving parts, or thin polycarbonate overlays to wear out.
