♦The shell is made of high-quality flame-retardant and transparent materials, which is strong and wear-resistant, resistant to high temperatures and corrosion, and is dust-proof and safer.
♦Widen and thicken the overall silver alloy contacts, which can carry greater current, have stronger conductivity, sensitive response and long electrical life.
♦High-purity copper coil can withstand large voltages and has a long service life of more than 10 million times.
♦High-quality nickel-plated environmentally friendly screws, translucent and rust-free, with stronger electrical conductivity and tighter wiring with gaskets.
