No generic brands but unless they are really totalled you can pull them apart and fix them.You take the rocker switch part that you push on first by prying on each side of it.... then unsolder the led and resistor, release the bottom of the switch assembly my releasing the 6 or so barb like clips and the whole show should now be in pieces.Just clean the offending contacts and reciprocate.But if they are bad secondhand is the cheapest way out but I suppose you risk buying one with the same problem....although for the money of a new one it might be worth the risk.
The contacts burn because all the current of the windows goes through them and if you are prone to leaving your finger on the button after the window has fully gone up it will bugger them quicker.I installed a relay in the up part of the circuit so the drivers window switch didnt bugger up again.
