Without stripping or soldering, just insert the wires and press them with pliers, without disconnecting the circuit from the electrical installation, very fast and light. This splitter is used to divide a circuit into two or two into one, so that one of the four holes is not live. Safety insulation stamped design, two-pin locking, no loose appearance, light and beautiful, withstand high voltage. The connector is made of polypropylene insulation material (for stability and chemical resistance) and brass terminals (for electrical conductivity). The plastic material of the quick connectors is flame retardant and environmentally friendly. The brass is protected by zinc plating, which prolongs the anti-rust period, increases the service life and does not affect the conductivity. Wide Applications: Suitable for universal detachable cable connections; Suitable for single or multi-core conductors up to fine copper wire; Suitable for demanding dustproof and conductive electrical systems. The connectors have different colors allowing you to easily identify them and choose them quickly.
