PCB - Daughterboard for Wiring 3PDT Footswitches
Our 3PDT PCB daughterboard (P-PC-3PDT-BOARD) is a small board designed to simplify the wiring of 3PDT footswitches in guitar pedals. All inputs and outputs are clearly labeled on the PCB, removing any confusion about how the footswitch should be wired, and decreasing the chances of wiring mistakes or short-circuits. There are dedicated pads for all offboard connections so that no pads or lugs require more than one connection. A dedicated location for an on-board current-limiting resistor allows for clean LED wiring with no floating resistor, whether you are mounting the LED on the board or using a bezel. Despite all this, our 3PDT board is one of the smallest boards available and can easily fit inside tight builds, including builds that use a 1590A enclosure. All pads on the board are oriented near their respective off-board components, which helps produce clean wiring and may even reduce the necessary space required for the footswitch wiring.
This 3PDT board has been tested and is known to work with:
The board will work with many of the common 3PDT footswitches that are sold, though we cannot guarantee a fit for any besides the above. It does not work with low profile 3PDT footswitches due to different pin spacing.

Those holes for the switch are tight! Those lugs are definitely making contact.
I intended that to be a 3 star review because of the lack of documentation, but between the page expiring and having to jump through hoops it reset it to 5 stars. The product is worth 5 stars, but lack of a schematic drops it to 3.
Nicely screened PCB but I wasn't finding any schematic that represented the printed circuit, only tutorial with an image of the board and a picture of how they intend it to be used. I had to draw out the circuit only to find that they reversed the pole and throw from how I was originally using 3PDT switches in a 2 switch circuit (Boost pedal with a Mute that also routes the signal to a tuner or other effect). That probably works flawlessly for some applications and I can rework the circuit slightly for one switch, but of the second switch I'll have to cut some traces and do some hand wiring. It's good for what it is and it's inexpensive, but documenting the wiring would have been nice it would be easier to tell whether it will work for a given application.
