I'm unfortunately not there physically to help, but my mom has this light switch she needs to remove temporarily and replace the plate. Her "handyman" installed it 'brand new' within the past few years. I told her it looked like it was from the 80s haha. Anyways, she apparently cannot remove the knob for the life of her, shouldn't the knob be able to simply pull off without breaking?
Looks like a tiny screw hole on the top.
I see what you're talking about, don't understand why you've been downvoted. I've seen both styles, and also a version where you have to pop-off the center-cap to get to a screw.
