Specification: Product Name: Pure Copper Double Pole Double Throw Switch Knife Material: pure copper plastic Colour: Black Weight: 47 grams Dimensions: base length: 74mm/2.91 inches; width: 60mm/2.36 inches; height: 10mm/0.39 inches; Package contains: pure copper double pole double throw switch knife *1

• Material: hard plastic, high quality pure copper, high safety, high safety factor; fine workmanship, high color value, durable, to provide students with hands-on experience to learn the principles of electricity and circuit.
• Safe and visual knife switch, switch provides stability, visualization of electrical principle, screw type binding post, tightening connection terminal is heavy, easy for wiring, for safe electrical connection; easy to reconfigure layout, enough for classroom.
• The terminal with knurled nut is used to fix the wire to the knife switch, and the screw hole is used to install the base to the worktable or panel; the excellent switch blade of double pole double throw is available for hobby, because it has exposed non insulating contact. Although it does teach them how electricity works, they must be taught not to use actual electrical equipment at home.
• These are low voltage, low current switches for low voltage DC power supply. 2.5 V, 3 A, 6 V max; double pole double throw electrical switch for making and breaking two simultaneous electrical connections; bakelite base for isolating current.
• It is very suitable for home school to make and break the single electrical connection circuit experiment; it is suitable for physics laboratory and school electronic experiment to teach the basic principle of electric power and simple circuit working principle, which are very suitable for demonstration and projects. Easy to use and suitable for children's learning tools, practice in the education model will certainly benefit any student.
