Multiple switches controlled by one key lock

[da na]

Bit of a novice to multiple switches going into another switch so I'd like some help to see if any of this makes sense at all.

Basically, I want to add an electronic lock switch to my PC case to block the use of the CMOS clear button, reset button, and power button if it's locked. The key switch I'm thinking of using has two pins. 
Issue is, though, if I connected all the buttons to the same lead wouldn't they all just activate when any one is used? That is definitely not what I want. I assume I would need a key lock switch with 6 pins then? I'd connect the negative of all the switches to the board, and have the positive go through the button then the lock then to the board. 

Any help would be appreciated!

Car or truck ignition might be the best way to go

Ah thanks! Didn't quite think of that, was going for the traditional round PC key lock but could not find one with the spec I needed

Technically as long as you're careful about the polarity you can use a simple single pole switch to cut the ground line that's common to all of them.

I'm not an expert.
But all those 3 is pretty much activated by shorting 2 pins
And that lock switch is simply a breaker with a key, right?

If you press power button, then the switch under the power button will short + and -
Reset & CMOS won't fire up because nothing shorting their respective pins.

The lock is only breaking / connecting the line.
Dunno about voltage share though since they're all connected to each other at the lock.

Unless you connect all + line to 1 pin on the lock, and all - line to the other pin on the lock.

The 3 pin sets assume right is ground.

OK thanks for the diagram! I had assumed center was ground for CMOS, because it and the left pin have the jumper normally. But I guess the left pin is unused as I don't see a trace. 

Sorry for all the questions but, for pin 2 in the 2nd diagram on PWR/Reset, can I really leave that disconnected or would I have to connect?

Each of these switches will (normally) be shorting a pin to ground. So one of the pin of each header whould be the same ground. That's what you interrupt with the keyswitch, so only one needs to be connected.

 

Use a multimeter to find out which is ground / make sure that's indeed how it works particularly for the cmos one.
