Strowger switch
A strowger switch is a machine that helps people communicate with each other through a telephone. Imagine you have a lot of friends, and you want to talk to them on the phone. You can't talk to them all at once, so how do you talk to just one person?
Back in the olden days, when you picked up the phone, it would be connected to a person who helps you make the call. But then, the strowger switch was invented. It's like a really smart machine that helps you make the call instead of a person.
When you want to call someone, you pick up the phone and dial a number. The number goes into the strowger switch, which is like a giant brain made of lots of tiny switches. The strowger switch then figures out which phone number you want to call and connects you to that person.
It does all of this really quickly so that you can talk to your friend on the other end of the line. The strowger switch changed the way that people talk on the phone because it made it faster and more efficient. Even though they don't use it anymore, it was really important in the history of communication.
