You are correct for some but I do recall some with a composite output in
that little switch box as well. Maybe I'm misremembering from 50 years ago.

The roots of this standard go all the way back to

became a standard in 1940. By passing the tuner meant bypassing all
of the filters and demodulation that needed to happen. Many video
games of the 70's and early 80's came with 300 Ohm antenna leads and
an RCA plug with a switch for modulated or unmodulated signals.
That little switchbox was so that the RF input of the TV could be
switched between the [normal] antenna, and the RF modulator of the
Computer/vide game. With almost all of them, the output was to the
TV, and the inputs were antenna VS computer/video game
Without that switch, if they were just hooked in parallel, then the
output of the computer/video game could leak/boadcast out of the antenna.
