Tips: What is a knife switch?

A knife switch is a type of electrical switch used to control the flow of electricity in a circuit. It consists of a metal lever, often shaped like a knife, that can be manually moved between two positions to either complete or interrupt the electrical connection.

The knife switch typically has a hinge or pivot point at one end, allowing the lever to swing up or down. At the other end of the lever, there are two contacts or terminals. When the lever is in the closed position, the two terminals are in contact with each other, creating a continuous path for the electric current to flow through the switch and the connected circuit. When the lever is moved to the open position, the terminals are separated, breaking the circuit and interrupting the flow of electricity. 

Knife switches were commonly used in early electrical systems, especially in industrial and laboratory settings. They were often mounted on panels or boards and had large, visible handles for easy operation. However, with the advent of more advanced and safer switch designs, knife switches have been largely replaced by other types of switches, such as toggle switches, rocker switches, and push-button switches, which offer greater convenience and reliability.
