I fly a C172S that has several switch type CB's installed for items such as certain lights. To turn the switch on in order to operate the system, the switch is selected up. Perhaps it is obvious but if a CB 'pops', does the switch actually move downward by itself. One might think that they forgot to select the switch on after an event and attempt to select the switch back on.

Had that happen to me in a old C150. Noticed avionics switch was flipped down after instructor got out, thought he accidentally hit it. Took off and radios quit working about 3 minutes later. When I reached down to turn it back on it was hot to the touch and started to smell like it was burning. Turns out those breakers weren’t supposed to be “switches” but instead we’re supposed to be the type that pop out when tripped.
