The lever type wire connector is made of PC nickel chromium steel, offering long service life, corrosion resistance, aging resistance, and electric shock resistance. How to use 1) First, strip the wire. 2) Push the orange lever up to 90 degrees, insert the wires, then push the lever down. 3) When the wire is inserted into the lever electrical connector and locked, the wire will not loosen. The wire butt terminals have strong pull resistance. Quick connect and disconnect Electrical wire connectors allow fast wiring and removal. To wires, lift the orange levers, remove the unwanted wires, and insert ones. Each connector surface includes a test hole to check whether there is electricity in the wires. Benefits and characteristics These lever wire butt connectors minimize wire messes and eliminate the need to twist multiple copper wires together. The splicing connectors are compact, easy to use, reliable, and reusable. They are effective at releasing the heat generated by the connected wires. Use scenarios Automotive electrical work: quick, secure connections in wiring harnesses without heavy twisting. Home appliance : fast replacement of damaged leads inside devices while maintaining safe, locked connections. Electronics projects and DIY wiring: convenient, reusable connectors that simplify prototyping and maintenance without compromising reliability.
