My cell phone app, bug detector scanner came up with a hit on this light switch in my office. I won't get into the why, but it wouldn't be a shock that my office could be targeted for a bug. I tested the device in every other switch on this floor, all offices have the same switch and none came back with that high frequency uT reading. Attached some pictures on what I see when I took out the switch. Anything here look out of place? Is there possibly another reason why this is giving off such a high reading when others don't?

I've attached pictures below.
