[2021] Demolition Dudes

When they were first introduced, Most traps could trigger them- Blade traps set at chest height would; blade traps at leg height wouldn't in most cases unless the zombie ragdolled in a funny way. Dart traps wouldn't trigger it from back, sides, top or bottom; but would from the front, shotgun turrets and smgs were dangerous to use against them unless you could guarantee they would only fire at the rear of them. Electric fence couldn't trigger it though. Even zombies could strike the detonator while swinging at other things.

However I've heard tell from others that in A19.x the demos no longer trigger from blade/dart/turret traps; only from player actions and possibly from junk turrets. So you'll have to wait for more input on that.. I haven't personally encountered demos in A19.x yet due to being occupied with other things.

Note that for player actions, ANY action can hit that button, even melee. So aim carefully.
