Knife switches are most closely associated with horror films set in the 1800s, especially in underground laboratories such as the one depicted in Mary Shelley’s novel Frankenstein.

Simply connect the ends of the circuit to the two metal screw contacts on the switch and instantly you have mechanical way of breaking and connecting a circuit.
