Wire pops out?

Take the switch off the wall and the wiring.
Look at the terminals and tighten them up with a screwdriver, do both terminals fully close? Do the terminals screw / tighten correctly?
From the simple tests you will then know:-
Is the thread knackered
Is the terminal screw not fully tightening
If everything appears ok you could find that you are not pushing the wire all the way into the terminal and when you attempt to tighten the terminal on to the wire, the wire is being pushed out of the terminal rather than staying inside it.
If the terminal tightens, but there is a slight gap at the base try bending the bare wire in a 180 deg loop, This doubles the size of the wire for terminating and can resolve issues where the terminal hasn't enough wire volume to bite on to

If it is just the screw not grabbing I'd suggest you bend both conductors, but don't twist them. This is just my personal preference, before people start shouting

I had that yesterday on a piece of equipment.
Some terminals need to be fully opened before putting the wire in other wise the wire goes under and not in the opening that closes up when the screw is tightened.
It may sound obvious but it does happen.

just checking im right, going by the instructions
red= live in
black= live out
now the neon light has come on, but nothing worked, so i moved it a bit and the light flickered, but keeps on going off, ive taken it off now and going to try and put it back on, what would happen if i switched wires round, would it not work?
5 min job turning into a nightmare. + its dark and im balancing a torch on my shoulder

If the ring has a crack in it it may appear to tighten but is easily worked loose when angled pressure is applied by the wire bening when you fit the switch. This forces the ring open and the wire pops out. Turning on off could also cause the wire to heat up and expand the ring, turning off has the opposite effect and the wire loosens over time.

it seems to be working now, i was just worried on which wire goes were, ive stuck to the instructions and it works so they must be right.
out of curiosity if i put the wires the other way round, would the unit have worked?
thanks for all your help.
