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.

Thanks Arun. Any chance you know a part number for something that would work?

probably he's asking for part number from "Digikey" or "Radioshack" catalogue]]> Arun Kumar V<nura1002003@nospam.com> Fri, 27 Jun 2008 18:49:47 -0700 http://www.8051projects.net/forum-t10282.html Re: piggybacked switch http://www.8051projects.net/forum-t10282.html 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.]]> sashijoseph<sashijoseph@nospam.com> Sat, 28 Jun 2008 09:37:01 -0700 http://www.8051projects.net/forum-t10282.html
