Hello Mac,

it would require a lot of mechanical alteration between a switch and a normal pot to achieve what is shown in the diagram.

these kind of two-in-one pots are readily available in the electro stores, you can find this part in any old pocket transistor radio in which when you first turn the wheel, the radio gets on and slowly the volume also increases.

probably he's asking for part number from "Digikey" or "Radioshack" catalogue

If radioshack's accessible,you can look up here for the part no... http://support.radioshack.com/support_electronics/doc21/21562.htm

It's this one .. VR001 10974780 POT W/SWITCH P7389

Does the pot need to be turned down every time you switch on/off? Else you could use a normal spst for the switch.

Let there be music........
