Easy to install, no tools required. Plug and play, then finish. Different wires are managed separately, different diameters can be connected safely. Built-in test point, electrical test no need to remove the tape. Technological innovations reduce wiring time by over 50%. They are ideal for removable connections as soldering does not need to occur. Suitable for copper wires of size 0.084mm / 2812 AWG. Connect any combination of solid, stranded and flexible copper wire faster and more reliably. If you need to change other wires, you just need to flip up the small lever and take out what you need and replace it, which is very convenient. Made from of the best flame retardant insulation material Nylon PA66. With the advantages of long service life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardant, it can effectively prevent electrical leakage. Lever nuts are therefore safer than traditional metal nuts. The internal spring contact is copper material, special surface plating to prevent oxidation, low resistivity and better properties conductors. Spring clamp technology is reliable and does not fall off. Since the clamping force can be automatically adjusted with the thickness of the conductor, the contact of the conductor is reliable and is not affected by installation technology. Widely Application: It is widely applied to building wiring, such as used to control multiple lights by one switch. It is ideal for compact and complex applications.
