That's off the top of my head. You might need some sort of filter to prevent back EMF registering 'ghost' button presses.

Diode?

yep a diode would work, you could put one in series with one of the wires to your solenoid, you might have to experiment with the direction you splice it into the wire before it works. A diode will allow current to flow in only one direction, should prevent back emf problems. Again, ask at an electronics hobby shop for advice on a diode rated for that use.
H4CK3R:
You could use a Diode...
But I have tested these. While you give current / power to the solenoid, it does not cause any power to transfer to the switch/ ipac, it just closes the circuit.
Here is the diagram i wrote.

Cool, looks like a cheap fix. http://www.radioshack.com/family/index.jsp?categoryId=2032269 :cheers:

There you go, check H4CK3R's wiring.
H4CK3R:
OK.. he's having a small issue, even with the diode hooked up.
He's still getting random keystroke entries, while mine isn't.
Differences are Mine are hooked up to a laptop power adapter, with the magnetic ring around it, while his is hooked up to a secondary PC power supply.
What is the best way to protect it for EMF's?
Is it EMF causing the the random keystroke entries?
Kinda at a lost here.

EDIT
here is how we tried with a Diode..
