SAFE - This kit includes 10 PC compact wire connectors, selecting the best PA66 modified nylon flame retardant insulating material, which has long service life, no corrosion, anti-aging and 4KV pressure and shockproof EASY TO USE - First remove the wire sheath (9~10mm), just push the orange clip up 90 slightly, insert the cable and turn off the switch. Instead of traditional electrical tape and intertwined butt connectors, technology innovation reduces wiring time by 70%. CONVENIENT - These wire connectors with 2 ports -4 ports are universal for hard and soft wires. You can use them to control multiple lights by one switch, 2 in 4 out. WIDELY USED - Universal connectors: They are suitable for solid wire with 0.084mm/28-12AWG and for flexible wire with 0.082.5mm/28-14AWG. It is widely used in building wiring where space is limited for all the connections requiring. REUSABLE - Each connection terminal has a sense connection and can also be recycled. Each independent junction shrapnel, different wire managed separately, different diameter can be connected to the safety. There is a test hole in each connector surface, Tip: bilateral pressure rod terminal, connect the positive pole, negative pole and power supply ground respectively.
