Members diocide Posted August 8, 2010 Members Share Posted August 8, 2010 So big thanks to those who responded to my earlier thread about replacing the switch in my phase 90. the part is ordered and on the way. But since I have this thing open, I figured I might as well change the LED... Seems easy enough, except I don't know which leg is + and which is -. Can anyone tell me? heres a pic so you know what version I have. Thanks guys! Link to comment Share on other sites More sharing options...

Members diocide Posted August 8, 2010 Author Members Share Posted August 8, 2010 Right, I knew that the long leg is + on new LED's, but I'm talking about which is which on the PCB... Link to comment Share on other sites More sharing options...
Members melx Posted August 8, 2010 Members Share Posted August 8, 2010 Right, I knew that the long leg is + on new LED's, but I'm talking about which is which on the PCB... feel for the flat edge.. that's the negative side. it looks like the bottom on that pic.

Members andreas Posted August 8, 2010 Members Share Posted August 8, 2010 The flat edge (negative/cathode/short leg) is closest to the switch. Take care when desoldering the old one (as well as the switch) - the holes are through-plated, so there's solder all the way through, and it's easy to damage the holes.
