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. This mini single knife switch allows for a circuit to be live or to be turned off. Simply connect the ends of the circuit to the metal screw contacts on the switch and instantly you have a mechanical way of breaking and connecting a circuit.

Features:

  • Easy to operate lever
  • Can control a circuit
  • Great teaching tool for teaching the basics of electricity

I'm working as a science coach for elementary teachers and always recommend Xump to teachers who want an inexpensive place to buy lab supplies. These are cute, work, and are cheap. Thanks, Xump!
