Looking for a...

[rawfuls]

Hey guys, looking for a key switch that has 2 positions, and will only be able to remove the key in the off position. Should be flat keyed. Prefer it to have 90 degree turns, too.

Long story short, want to use this key switch to activate my computer power button, without the key the computer cannot be turned on.

I see to be able to find 2 positions spsts, but with the key able to be roved in both positions.
Must be panel mountable.

Thanks for any help..
