SD1 electric windows and DIY wiring

My car came without electric windows, so I retrofitted motors from an SD1.
But for the switches I made my own setup using simple buttons from ebay and some reasonably clever relay wiring. I actually used the simplified version with the diodes

The original simple circuit has a fuse and switches which don't seem to give lot of trouble so why go to such bother unless you cannot get the original switches now.
