I've changed several of them. The biggest problem is getting the exact same switch for physical mounting purposes.
I've had luck in the past by taking the make and number off the switch, and then do a search on the net. I've not had much satisfaction by going to the jack manufacturer.
When I find them, I usually buy two.
