Google 4 pole switch for some new ones.
Home Depot has some in stock at my store.
You can basically wire the bag kill switch lines together. Cut the switch off and wire nut them. As long as they are connected, the power isn't "killed".
Double check the other electrical as well. There is a tiny breaker that may have popped if you get to the point and nothing is working.
It is underneath the little circle plug on the right side of your case.
As for switches...
I put mine under the face next to the bag chute so i can keep my hands down low where the beans come out and where the cleaning lever is.
