An Electrical Knife Switch is a simple, manually operated switch used to control the flow of electricity in a circuit by making or breaking the connection. It consists of a metal lever, or “knife,” that pivots into or away from a contact point to open or close the circuit. Commonly used in industrial and laboratory applications, knife switches are ideal for high-current loads and manual control. They are available in single-pole and double-pole configurations and are primarily used in power isolation, testing, and circuit switching. Knife switches are valued for their durability and simplicity.
