Sorry, no photos.
But something from your photos.
Brown in is possibly a fuse, it goes to diode.
Blue in can also be a fuse, it goes under the button and space is too small for black diode used elsewhere.
But blue in wire shouldn't touch the 100k resistor, it might be so in first picture.
Other side of the button is a black diode.
If it's positive end is directly connected to blue in there is a full wave rectifier of some sort.
Half wave rectifier there clearly is since brown side diode is the only thing through what electricity goes.
The side also seems to be straight through, return is unknown.
