Does anybody know where can I source this kind of switches?

Edit: Regarding S.P.C.O type switches. Is the switch always connected to one terminal? I'm looking at some Bulgin SPCO switches and I'm wondering if they work as normal push button switch.

Yes, it's surprisingly hard to find nice push button switches. I think the Bulgin is only a monetary switch. It might be better to get a standard switch and just look for a nice cap to make it look pretty. Maybe just use a small volume knob (without a volume marker) would do the trick.

Check out APEM, especially their AV-series. Their AV04-model is 2-pole On/On type switch.

At least ELFA carries both Bulgin and APEM switches. (Electromechanics/Pneumatics -> Switches -> Pushbutton switches -> Show product images) Although ELFA operates only in Northern Europe they do ship internationally.

You might also check into the PC modding world. I'm sure someone is offering something that might suit your task well.

you can always buy a cheaper switch with a long straight stem, and find a button/knob that fits and suits your tastes.

Run searches for vandal proof (!) switches and you'll find results like these:

I think that's what you're looking for. I don't know why all the nice pushbuttons tend to be the vandal proof ones, but they'll sure hold up if you have small children!

I worry that the vandal proof switches might have too heavy an action for our relatively light-weight amps.

I was browsing Allied's inventory for switches and I found a Schurter SPCO switch (bulgin look alike) that fites my purpose..it's only 19mm in diameter. Cost about 9 bucks for the switch but heck it looks awesome. Now I just need to find a dual/tri color LED that I could use as the indicator for power on and off - aint that awesome?

The amp im building will be rather heavy...shouldnt have much problem with the switching force required.

SPCO means single pole change over? Isn't that just the same as a SPDT (single pole double throw)?

Apparently it is

In some cases it can mean single pole center off, but either way it's still just SPDT.

Dunno if it's what you're looking for, but this is the coolest pushbutton switch I've come across:

I'm using one on my F1 clone:

It is momentary so requires some circuitry if used as an on/off switch.

*edit* oh... looks like this is a bulgin. I didn't even notice. Sorry if this is redundant.

You can pick up those bulgin switches at Mouser in other colors as well (red and green IIRC)

Could you expand on the circuitry needed to utilize this switch as an on/off?

The examples in the link are pretty application specific but you will get the general idea
