QTY:
 

Knife switches are associated most closely with horror films and books set in the 1800s, where they can be found in underground laboratories such as the one depicted in Frankenstein. This miniature single knife switch is compatible with circuits, and allows for them to be switched on and off.  Just connect the ends of the circuit to the metal screw contacts on the switch and you will have a mechanical method for breaking and connecting a circuit.  This pack contains 10 switches, allowing you to build a plethora of circuits with multiple swtiches and connections!

Features:

  • 10 mini knife switches
  • Very easy to operate
  • Can be used to connect or break circuits
  • Great teaching tool for teaching the basics of electricity

5 star rating  Very Good for school
Gil K from Nevada City, CA.USA
They are very good switches. They are a little smaller than what I hope for. I wanted then for my LGB trains. I think I will end up using then for my Lionel trains. I will be using them for sure and I may end up getting more
