I could not get my switch to be snug either as one of the tabs was broken off. I tried with a tie wrap too. In the end, I used a dremel tool to cut small grooves in the sides so I could twist it into place like a bayonet fitting.
It has worked for several months now though it was very intermittent until I sent it off for repair.
