SAFE AND RELIABLE: The terminal is made of flame-retardant PA66 (pull rod) / PC (shell), and the internal conductor is made of nickel-plated copper, which is flame retardant, corrosion resistant, aging resistant, high voltage resistance , long lifespan, etc. Features. It can prevent leakage, safe and reliable. ANY COMBINATION : a total of 34 SPL-1 wire connectors, a new sliding button combination design, electrical connectors can be freely combined and can be spliced into 2/3/4/6 way docking cable connectors. REUSE: Each terminal has a detection connection, which can also be recycled. Each connector has independent shrapnel, different wires are managed separately, and different wire diameters can be connected safely. There are test holes on the surface of each connector, and the electrical test can be carried out without removing the tape, which is intuitive and convenient. EASY OPERATION: First remove the wire jacket (9~10mm), just push the orange clip gently up 90, insert the cable and turn off the switch. Technological innovations have replaced traditional electrical tape and interleaved butt connectors, reducing wiring time by 70%. WIDE APPLICATION: Widely used in building wiring, such as a switch for control multiple lights. It is ideal for compact and complex applications. The universal connector is suitable for solid wires of 0.2 ~ 4mm/AWG28-12 and soft wires of 0.08 ~ 2.5mm/28-14AWG. Note: The data is all measured manually, please allow 1-3cm error due to differences in light and display, there may be some color differences, please refer to the actual item received.
