Sounds like stoat is something you order when you go to a bar, "hey bartender, give me a tall cold stoat".

"A Weasel is weasely distinguished, as a Stoat is stoatally different!" ;D

It's cruelty to animals ... Permitted in Australia?  :scared:

When set up properly, in the box with baffles & all, they're (a) pretty impervious to larger animals sticking a random paw in & getting it smooshed, and (b) fairly humane in that they're designed to kill animals of the target size instantly.

Here's a NZ DoC brochure showing the usual setup. (pdf)

FWIW I've seen car interior light switches used on live cage traps to trigger a transmitter in cases where you don't want the animal to be trapped & vulnerable for too long (e.g. where there lots of predators, like dingoes, that can trash a small trap). They're pretty well sealed to start with, and a bit of silicone sealant or 'blackshit' (self amalgamating tape) works well enough on the terminals / connectors / entry holes. No problems in coastal Australian bush/forests/swamps, though admittedly it's probably drier than most NZ bushland.

firstly thought about a button used on the 3D printer... or IR detector  to detect the trap location(trapped or not):

The animal is well dead almost instantly.  the reason for the notification is so you can go and reset the trap, to catch the next one.
