Displacement connectors like that are notorious sources of intermittent connections. The best fix would probably be to cut and strip the wire and then crimp the two ends in a standard spade connector and push it on the switch terminal. Soldering the two wire ends together before crimping wouldn't hurt either.
I agree with this. Why replace a connector that is clearly not lasting well with an identical one that likely also won't last too well when there are other simple alternatives that do work well?
Another alternative (what I initially thought of) would be to run a pigtail to a spade connector and splice the three together, but Dutch's solution sounds simpler and probably more trouble-free to me, so I would go with that.
