Looking for a switch

So I've been looking for a few hours now and I'm at a loss.

I need some assistance looking for a normally closed momentary push button switch capable of ~500mA that will fit in a 10mm x 10mm x 5mm area.

I'm pretty much at a loss, and I really don't want to try to make a switch, especially that small.

Any ideas?

I was also looking before but never found one. I ended up using a logic level mosfet and a tact switch. The mosfet is wired so that it is normally on and the switch shorts out the gate to turn it off. It does consume a small current at idle though but didn't matter since my laser has a key switch.

Thanks for the input! If I can't find a button that is rated for 500mA would a relay work? Has anyone used a relay with any success? I figure if I use a simple relay like THIS then couldn't I get around the switch being rated for 50mA and the need for 500mA? I have room elsewhere in the host for the relay, just no room for a bigger switch.
