"Don't Jiggle the Switch Hook"

1 min read

While doing some research for a project I'm working on, I came across this video in the Prelinger Archives: a 1927 film providing instructions on how to use the new dial telephones.

My favorite line:

"Remove the receiver carefully so as not to jiggle the switch hook."
