knife switch
Blade-contact electrical switch
A knife switch is an electrical switch with a hinged metal blade that swings into or out of contact with a stationary jaw.
The exposed conducting parts make it easy to see whether the circuit is open or closed.
Once common in homes and industry, knife switches now appear mainly in educational settings and high-voltage disconnect applications where visible confirmation matters.
