Which type of switches are they? The guarded ones are press fit and rarely come loose but can be broken. The AV switches are glued in on sabers without switch blocks and rarely come loose but the bezel they hold in often rattles making them appear loose.
Ah I see, well it is indeed the bezel on the av switches that have started rattling. So this is normal and they won't eventually fall out? And indeed it was my guarded switch on my stunt saber that actually broke. It sounds like you've had some experience with this, as those are exactly the issues I'm having
