Back when these amps were new a lot of wiring was ungrounded in houses and two prong plugs weren't polarized. You saw a lot of this type of thing in electronics. You set the ground switch for the lowest noise. If you were performing with other musicians with their own amps and PA's you ran the risk of getting a pretty bad shock if you touched another instrument or mic and you didn't have the ground switch in the right position.
Today we call that a death cap. If you own one of these types of amps, cut that cap out, disconnect the ground switch and install a proper three prong power cord.
