Replacement power switch

The power-on switch in my In-Win case has failed. I thought that it would
be a trivial thing to locate a replacement switch, but I've had absolutely
no luck. Can anyone point me to a source? I don't want to get rid of my
case: (A) I like my full-tower and (B) doing so simply because the power
switch is out seems insane.

Thanks,
Alan

RadioShack switches:

Momentary pushbutton - solder the "NO" (normally open) and "COM" terminals
to the wires on the Inwin harness. Remove the Inwin switch, and connect two
of three pins of one of these:

These, by comparison, are pure misery and do not buy. Spring force is
too high. I've tried these and don't like them. The 2062541 above, at least,
looks to be based on microswitch technology. Not quite as cheesy.

Mini SPST 0.5-Amp Momentary Switch (four per pack) - normally open, two terminal

So what you want, is a normally open, momentary contact switch. Switches
with three terminals, have a "NO" (normally open), a "NC" (normally closed)
and a "COM" terminal, so with the three contacts, you can either make
a normally open or a normally closed switch. You'd use "NO" and "COM" to
make a normally open momentary contact, to switch on a computer.

The ampere rating is not important, because the current involved for the
computer switch, is 0.001 amps. None of these switches, not even a reed
switch, would be bothered by the current flow.

To install the switch, you have a couple options. If you are lucky, the
switch hardware just fits the hole. Or, you can drill a fresh hole, of
the correct diameter, and leave the old switch in place, so no gaping
holes are left. Note that, if you want to drill a computer case, remove
*all* the hardware first. Drill the hole, vacuum thoroughly when you are
done. No sense having a motherboard short out, when some aluminum or steel
flakes, fall into some IC pins.

Thanks much.

Actually, I'd like to replace the switch with a rectangular rocker-type
switch, but this helped lots. Thanks again.
