This is great for home school making and breaking a single electrical connection circuit experiments. good for teaching basic principles of electricity & how a simple circuit works.these are great for demos and project. Easy to use and great learning tool for kids.I think practicing on an education model would definitely benefit any student.

of course that while this does teach them how electricity works, you have to make sure to teach them not to play with actual electrical equipment around the house.

switch provides stability in handling and visualization of electrical principles, screw type binding post ,screw down connection terminals are heavy duty,for secure electrical connection.
