Hi,
I've lurked on these boards for years and years and years now. I used the original BYOAC to help me restore my MAME cabinet back in 2002 and I've used this site for many of my own projects. Just wanted to show a quick bit of appreciation.
I'm currently consolizing a Sega Game Gear (that is, modding it for TV-out support and building a gamepad, and placing it in a custom-shaped box). I plan on having my console match the look of the Sega Master System:

For those who have never used one, the large square button on the front left of the machine is the power button. It behaves like the power button to the old toaster model NES - a button that can depress on or off. I'm having trouble finding a pushbutton that behaves like this, and I'm not sure what the exact sort of name for that kind of pushbutton would be. I want to wire the on/off switch from my game gear to this sort of pushbutton starter.
Could anybody recommend a brand and type of pushbutton that behaves like this? I specifically need it not to be momentary, i.e. when you press the button, it clicks in and remains pressed until you unclick it by pressing it again. I'm looking for something preferably about 1/2" x 1/2" square in shape and size.
I figured, as always, this site would be the place to ask. Appreciate any responses in advance.
