Re. the "pinch protection" that keeps being mentioned - if the previous system only stopped when obstructed, I can't see it being an essential requirement for the replacement. It would be different if the older one had that.
I suspect it's more a requirement for "one touch" window controls that continue to move after the button is released.
A polyswitch is not perfect, but a more advanced system requires limit switches or digital position tracking, as well as current monitoring..
I do agree, by those said here that this "polyswitch" is my best option comparing function vs simplicity. I will try and see how it goes.
Of course I don't have "problem" if more ideas/options keep pouring in
Question: Given that the window motors have two wires with polarity changing depending if they go up or down, do those polyswitches have a polarity preference or can be conneted either way?
You are right regarding the "pinch protection". More needed in the "one touch" mode that I don't have at the moment. I have in mind of doing it but, altough I do have the needed relays, I haven't tried it yet.
And speaking of "one touch", I have a few from Ford (Mondeo perhaps) as i was planning to do the "one touch" even with my previous setup (the spal electric motors).
They are these:
Although I have seen those relays been used in "one touch" retrofitting to other cars, I haven't found yet the correct pin-out. There are models that have 4 wires and models, like the one shown which I have, that have 5 wires.
I have looked in various places (even ford forums) but with no clear answer as to what each wire represent or possibly a connection diagram.
Any ideas?
