Evan Fischer brand?
I bought the switches off Amazon and they work fine. I can’t remember the exact brand I got, but it was about $26 for 3 switches. I used the internal guts of the new switches and re-used the external shell of my original units because they felt slightly more substantial, but that could be my imagination (or bias since my mind knows they’re factory Porsche parts). I packed them with dielectric grease and they work great! The factory switches’ guts were all worn out and the windows worked intermittently.
