harps Posted July 18, 2012 Report Share Posted July 18, 2012 hello I am seeking a quiet led push switch that can give red, green and orange (red + green). The MEC 3f quiet is no longer available. are there any other quiet switches available that people are using? thanks for help : ) Quote Link to comment Share on other sites More sharing options...
Lamouette Posted July 18, 2012 Report Share Posted July 18, 2012 (edited) i don't know what is the use for, but care with the mec switch, they don´t have common cathode. all is explain here : if it's for a BLM, i would to use Livid instruments pads, but as the conductor ring is a bit little you have to cut it for use it with 3 legged led (with common cathode, so red green and orange). maybe the solutions is to use SMD leds... i will restart to work on it when weather starts to be sad ! here in Canada, winter was been created to work on Midiboxes ! :tongue: Bye Edited July 18, 2012 by Lamouette Quote Link to comment Share on other sites More sharing options...

Lamouette Posted July 18, 2012 Report Share Posted July 18, 2012 yes, gold applied on the PCB could be nice (and more solid than normal trace). (i'm at job so i can't see all the thing you put on your post) I already worked a bit on a trace for the 3 legged led + livid buttons, but it's not really easy. the part have to be usefull in a lot of project (like the BLM), and fit perfectly with a full pad (8x8) of livid buttons. so it must be suffisant large to have a good contact, and suffisant small to fit perfectly, and let some space around and between the others trace around ! i'll search tonight, some relic of my work om it. If we could work together to find a good solution, it could be really nice and fun ! and usefull for the community of midibox ! :ahappy: Quote Link to comment Share on other sites More sharing options...
