I’ve never seen that before, you should definitely get an electrician to look at it as the idea of a loose wire scares me

Looks like a 3way light switch is needed based on those 3 wires, is that what you installed?

The switch works, the wires are the correct ones, then the last owner might have done some weird bypass. Can you show us the wiring more clearly? Try to get a good picture of where they come from and where they go

Are you sure your switch is for the lamp?

Are there other switches for the same lamp?

More of an emotion classification system

When it learns what this means it’s going to be in a sad state
