your used 32 red buttons panel board is for short distance use, it usually used in a Power Distribution Box inside. the board only support <5 meter from the switch panel, and need to use thick line , suggest use shielding wire. But I seen you have use the CAT5 network cable, if you have use this cable, we suggest use "switch terminal board" -- last photo, it's very stable and for long distance, support 300 meter from the board to your wall switch panel.
