Very simple breakout board for 16mm 4 terminal(solder lugs not screws) LED momentary buttons.

Have you grown tired of soldering through hole resistors to the terminals of your buttons, then soldering wires on top, which makes it impossible to heat shrink so they always come out looking sloppy -_- Well fret not! Simply solder the required 220 Ohm(adjust if necessary) 0805 resistor to the PCB, then simply connect the ground, in, and out wires(you can also connect the voltmeter positive to the extra pad if you’d like it to turn on when you press the button), then lay the PCB on the button with the resistor side facing the button, and solder in place. That’s all there is to it!
