A knife switch consists of a lever and one or more sets of __________.

Explanation:
Knife switches work by opening and closing electrical paths through sets of contacts that the lever connects or disconnects. The lever moves a blade into contact with conductive blocks, completing the circuit when engaged and breaking it when lifted. That makes the contacts the defining element of this device. Coils, resistors, and fuses are separate components used for other functions—coils for magnetism or switching in relays, resistors to limit current, and fuses to protect circuits—but they aren’t what define a knife switch.
