How do you handle your campaign without a Rogue in the party and you want to incorporate traps?

For instance, if a switch is found behind a picture on the wall and it’s supposed to trigger a trap, how is that handled?

Can a non-Rogue character “understand” it’s a trap by investigating further? Can Discern Realities help with this?

Does the non-Rogue have a chance to “disable” the trap? I suppose a character could throw something at the switch from a distance away…

Maybe I’m answering my own question and the narrative helps dictate…
