What is the SW pad on Madbean PCB?

Is the SW pad just a ground so that the board will be grounded when the effect is off?

Also, can I connect my led directly to the led pads on the board rather than to the switch?

(a) What project are you referring to? SW is usually short for "switch" so it could be literally dozens of things.
(b) Look on the schematic for the project you're working on. The SW pad will be shown there.

in the newer project this is the solder pad that you connect to the 3PDT switch (thus SW) to switch your board-mounted LED on and off.
So you'll have your LDR and LED soldered directly on the board and then connect the SW pad to the respective row on your 3PDT switch. As an example, have a look at the new Nom-Nom build doc here. Here, the SW pad is labelled "L", but other than that it should most likely be the same with your project

Sorry, should have mentioned this.  I am building the MBP 2014 Rangemaster.  I am also using a Mammoth large 3DPDT pcb.  The switch pcb has a pad for LED.  So based on what M-Kresol said, it sounds like I should connect the switch pcb pad marked 'LED' to the Rangemaster pcb pad 'SW'.  Is this correct?  Then also connect the LED directly to the Rangemaster board....

Let me know if you would like me to post an illustration.

You can either hook it up like shown on page 5 of the build doc or if you use the mammoth daughter board you need to run a wire from the SW pad to the "5" pad on the daughter board. This is with the LED mounted on the rangemaster board.

if you don't want the led on the board (because you dislike it's fixed position on the board layout) you can either run long wires from the LED pads on the rangemaster board and place the LED anywhere or just leave the LED off and not use the SW pad at all. Then you could use madbeans general wiring schematic (using the daughter board you'd connect the LED - (cathode) to pad 5 of the daughter board)

SW in all beans boards are intended to go direct to the switch where the led switch to ground

Got it.  Thanks so much for the help.
