Thank you very much for the circuit. I can deduce from the images that the first switch is for powering the circuit, the second current selector and next to it the dc output potentiometer, but... and the last toggle switch, what is it for?

Could this use to permanently power backlight on any given LED tv practically otherwise from test?

Hi, it is a cool design. Could you tell me where is the other end of R13 connected to, please? The line on the schematics is unfinished. Thank you.
