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 double knife-double throw switch allows for up to two circuits to be live or to be turned off. 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.

Features:

  • Easy to operate lever
  • Two pre-drilled holes for mounting
  • Great teaching tool for teaching the basics of electricity

Customer Reviews


4 star rating  Not quite as expected.
Wolf Gray from US, VA, Hampton
Device was flimsier than expected, while I wasn't expecting "Throw the switch, Igor!" levels of durability, I worry the device won't engage properly. Action is smooth and knives engage, but the metal quality seems flimsy and you don't want to move the switch quickly.
