[ Widely used ] - The dual wire push-in connector with lock buckle is suitable for almost any normal household wiring: ceiling fans, sockets, switches, cars, motorcycles, ships, speakers, lamps, etc. Widely used for building wiring, saving valuable space for all necessary connections. [Practical and neat] - The voltage range of the connector is 0.08-2.5mm2/28-14AWG. They hardly ever mess up the ends of the wires, keep the electrical box relatively spacious, and don't have to twist a bunch of copper wires together. [Reusable and efficient] - Suitable for both soft and hard wires. Each connector is designed with for different wires. And for safety reasons, different diameters can be connected. Double wire push-in connector with locking buckle - The double wire connector is made of PA66 nylon and has a certain degree of thermal stability, making the plug and wear-. Copper is modified with the best flame-retardant insulating material, which has long service life, no , aging resistance, voltage resistance and resistance. [Easy to use] - Reduce wiring time by 70%! Just lift the handle, insert the stripped wire, push the handle up, hold it tightly, and firmly connect it. [Convenient] - There are test holes on the of each cage. There is no need to remove the tape during electrical testing. It is intuitive, simple, and reusable.
