Hard to answer in detail without knowing what it's supposed to do, but it looks like an arrangement to allow whatever's on the other end to read the switch and also detect fault conditions such as an open or short circuit. It's expecting to see one of two resistance values, and anything wildly outside that range means something is wrong.
