Hi, does anyone has a 9V switch as a .DAT file, unfortunately can't find any on the LDRAW site, nor in official, nor in unofficial parts. Does anyone has it and may tell me the link or send it as file? Why do I am looking for that? I want to include (...) (19 years ago, 20-Aug-07, to lugnet.cad.dat.parts)

(...) Let me check I understand the theory of this - you want 1.5V across the LED, which means the resistor has to take the other 7.5V. You then pick a resistor that gives you a 20mA current at that figure of 7.5V. Then you double-check the power so (...) (19 years ago, 20-Aug-07, to lugnet.trains)
