Problem solved. Thank you all.
is it a momentary one?
The key switch?
Not sure - link is in original post it says; SPST 2 Position Random Key Switch
i would look for a momentary one trust me it will be annoying turnig the key then quickly turning it bak to keep it powered on
Yeah, if it's not a momentary switch, leaving the key in the "on" position will start up your comp, then shut it right back down, rinse & repeat, just like when you mash down the power button and hold it.............
You should do what did, wire the key switch in with a normal power button, so that the button won't work unless the key is on the on position. Sort of like starting one of those expensive cars.
there is alot of momentory ones look for sping back keyswitch on possible google
yeah, but wiring the power buttons in series with this one (ground of course) ; you can fire up each computer apart, but only if the key is in the lock (and turned?)
Off the top of my head I *think* if you used a flip flop, with your key switch as one of the inputs, you could connect it to the trigger of a 555 monostable. The result would be that the circuit would produce a pulse when there is an edge change, be that rising or falling.
I'll have to test it out when I go home and run a multisim simulation. Suffice to say, there will be a way of making a latching switch work with your PC, but it depends on how much you can be bothered making a circuit for it. The simpler option, be far, would be to use a momentary switch. Or using Stuarts idea for linking the button in series with a normal power button.
I have already purchased the switch, so i don't really want to buy another (momentary one) unless the one i've got now is going to be too much trouble to get working.
I'll go with an easy option.
OVERKILL OVERKILL OVERKILL OVERKILL OVERKILL OVERKILL OVERKILL OVERKILL
Just put it into series with a momentery pusch switch.
OK, so since i don't have a momentary switch, and i'm not buying one this looks like the best way to go about things.
Anyone got any experience with this stuff?
What everyone is saying is, on the circuit for the switch you have currently(a normal case switch) put the lock switch on with it.
all in series!
That's easy, here's how I did it...
-- Take your push switch (I assume it's wired)
-- Chop one of the wires, I would say positive (how far down you cut will depend on how far the key switch is with the push switch)
-- Solder the cut wire still attached to the push switch onto the negative terminal of the key switch.
-- Solder the wire left over onto the positive terminal of the key switch.

Not really, its only 2 IC's and a bit of wiring, the entire circuit would only measure 2 inchs by 1. If he really wanted to use the key switch WITHOUT wiring it in series with the usual momentary button then this is what he'd have to do. I did say:
I made a little drawing for you (MSPaint on W7 is much better):
