Hey guys, it's been a while but I'm back with a few updates on the project, but still bugged by the same issue.
Since last time I've made a PCB and tested for a few days with success but only when powered by an external battery, Here are some images:
When the board is powered by any source of power other than the battery (via the breadboard power supply or a cell phone charger), every time the Electromechanical Contactor is triggered, it also trigger some other random input on the board, even when there are no wires between the Contactor and the Board, just by being on the same electric grid those issues occur.
I'm pretty new at this, I've tried what martinayotte said regarding the external pull-ups and decoupling capacitor, but I'm not sure if I understood him right, so here's a picture(bellow) of what I did (the capacitor is connected on only one of the switches(above), but since it still randomly triggers it, my guess is that it's not working, so I haven't placed it on the any other switches).
