There are little clips (well, there is one of two left), but they prevent the switch from coming back out the top side. I don't think the switch is removable from the bottom side. Won't fit through the opening.
So this switch must have been wired into its plug after it was snapped into the bezel.
Unfortunately I can't figure out the release mechanism for the sockets in the plastic socket. Normally you can put a pin in the hole and then back them out. I can't get these to back out.
Might have to cut the wires and splice back.
