Higher security This wire connectors with 2 ports are universal for both hard and soft wires. You can use them to control multi lights by one switch. Selecting the best flame retardant insulating material modified nylon PA66, which has a long life, no corrosion, anti-aging and pressure 4KV and against electrical shock. Easy to operate:First remove the wire jacket (9~10mm), just push the orange clip slightly to the top 90, insert the cable and switch off the switch. Instead of traditional electrical tape and intertwined butt connectors, technological innovation reduce wiring time by 70%. Widely ApplicationUniversal connectors are suitable for solid wire with 0.08 to 4 mm2/ 28-12AWG and for flexible wire with 0.08 to 2.5 mm2 / 28-14AWG. It is widely used in building wiring where space is at a premium for all connections requiring. Can be reusedEach connection terminal has a detection connection and can be recycled as well. Every junction independent shrapnel, different wire managed separately, different diameter can be connect security. There are test hole in every connector surface, electric test can be completed without removing tape, intuitive and easy.
