[Safe and Reliable]: The terminal is made of flame-retardant PA66 (pulley) / PC (housing), and the inner conductor is made of nickel-plated copper, which is flame-retardant, corrosion-resistant, aging-resistant, high-voltage resistant, and has a long service life. It can prevent leakage, safe and reliable. Arbitrary Combination: A total of 34 SPL-1 cable connectors, a new sliding button combination design, the electrical connectors can be combined freely, and can be spliced into 2/3/4/2 butt cable connectors with 6 ways. REUSE: Each terminal has a detection connection, which can also be recycled. Each connector has an independent shrapnel, different wires are managed separately, and different wire diameters can be connected safely. There is a test hole on the surface of each connector, and the electrical test can be performed without tearing the tape, which is intuitive and convenient. Easy Operation: First remove the wire sheath (9~10mm), simply push the orange clip upwards 90, insert the wire, and turn off the switch. Technological innovation replaces traditional electrical tape and intertwined butt connectors, reducing wiring time by 70%. WIDE APPLICATION: Widely used in building wiring, such as a switch to control multiple lights. It is ideal for compact and complex applications. The universal connector is suitable for 0.2~4mm/AWG28-12 solid wires and 0.08~2.5mm/AWG28-14 flexible wires.
