Trumbull Electric Manufacturing Company Knife Switch, 1900-1920
01
Artifact Overview
Switches open or close an electrical circuit to turn things off or on. In the late 1800s and early 1900s, knife switches were commonly found in engine or generating rooms, connected to factory motors, or mounted on a building's power and lighting switchboard. Operators pushed the hinged, metal blades into the switch's jaws to send electricity to where it was needed.
