Atari "Volcano" Button Help
SirPeale:
The switch assembly isn't being made any more. People have made repro cones, however.
Level42:
Luigi from Germany sells repro cones, and both used and new switches for very good prices, although the Euro-Dollar rate may bring things up for the US folks here...

I have one in my hand as I post this. The left set of three have the NC and NO tabs labeled and the right set of two has the ground tab labeled. It also says they consume 0.1A at -125VAC.
-125VAC? Odd.

These are maximum allowable values. You have to calculate proper resistance, so the current to the led is <=0.1A.

I don't believe this to be correct -
The LED draw is not specified, this 0.1A is the switch contact rating. Allowing 100mA (at 100% duty cycle) to the LED most likely will damage it. While I don't know just what the rating on the LED is, most 'normal' ones are rated for a max of 20mA (0.02A). Usually only the 'superbright' ones are rated at more than 20mA. I have my doubts that superbrights were even invented 25-30 years ago let alone used in these buttons...
I suggest calculating resistance so that the current to the LED is limited to 10-20mA.

Todd at TNT Amusements has the buttons for $10 each.
