Can the later model switch work? I saw one today but it have 10 pins and the one i have is with 8 pins. What's the difference?

check on realoem the p/n you have, then click in there on the blue marked "i" at the left of the p/n, a new window will open which tells you Exchangeable retrospectively with old p/n.... or not exchangeable. As the other switch has 2 more pins, I doubt it will fit.
