XFFCSEC10PCS Knife Switch: for Physics Laboratory Demos Circuit Teaching | Circuit Switchs Great for Homeschooling Demos Teaching Basic Principles of Electricity & How a Simple Circuit Works

I was pleasantly surprised how much I like these knife switches. I am used to a much smaller design that has more metal. But the larger size of this switch made it really easy for the children to connect their wires and there is no confusion whatsoever about how to connect the wire. Great job!

Purchased these foe=r a 7th grade call to use to build electrical circuits. They held up very well and were easy to use.

These worked for our circuit unit. The only thing is that the orange pieces screw all the way off and students were taking them and throwing them/ dropping them. Other than that, they worked and help up to rough handling.

good value

Muy bueno

Good switches, and they came on time

The black and red knobs on many of my order simply spin and never tighten on the wire my students were trying to use. They ended up just sticking it on the underside as they could not get the knobs to work and hold the wire.

So far the switches have held up well with multiple uses by my elementary STEM students (grades 3-5)!
