4Pcs KV439 Lever-Nut Wire Connector Set, 3 in 9 Outputs Conductor Compact Wire Connectors, Compact Connector Spring Terminal Block

Easy to install, it is no need operated by tools. Just plug and play, and then finished. Different wire are managed separately, different diameter can be safely connected. Built-in test point, electric test no need to remove tape. Instead of traditional electrical tape and electrical butt connectors twist-type, technological innovations reduce wiring time by more than 50%. They are perfect for removable connections as soldering does not need to occur. Suitable for copper wire size 0.08~4mm²/28~12AWG. Connect any combination of strong, stranded and flexible copper wires faster and more reliably. If you need to change other wires, you just need to raise the small lever and remove what you need and replace it, which is very convenient. Made from the finest PA66 Nylon flame retardant insulation material. 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 conductive properties. The spring clamping technology is reliable and does not fall off. Since the clamping force can be adjusted automatically with the thickness of the conductor, the contact of the conductor is reliable and is not affected by the installation technology. Widely Application: It is widely applied to building wiring, such as it is used to control multiple lights by one switch. It is ideal for compact and complex applications.
