How to buy switches
Buy switches a, look at the appearance
Quality switches and sockets panel should be used in high-grade plastic products, looks like the material is uniform, the surface is smooth and textured. Panel materials are selected from the U.S. General Motors imported PC material (bulletproof rubber), its flame retardant, insulation and impact resistance are very good, and the material is stable, not easy to change color. Selection of such material production of switches and sockets, can greatly reduce the occurrence of fire caused by the circuit.
Buy switch two, look at the internal structure
On the switch, usually should be used pure silver contacts and silver-copper composite material made of conductive sheet, which can prevent the opening and closing of the arc caused by oxidation. The conductive bridge of the high-quality panels are silver-nickel-copper composite material. Excellent conductivity of the silver material, and silver-nickel alloy inhibit the arc is very strong, the switch uses a brass screw pressure line, the contact surface is large and good, pressure line ability, wiring stability and reliability. Single-hole wiring copper column, wiring capacity, not subject to wire diameter thickness limitations.
Buy switch three, safety
Socket safety protection door is essential, you should try to choose the socket with a protective door when you pick the product. Secondly, you should check the degree of fastening of the socket clamping piece, the insertion of a smooth force is a key factor. At the same time, the strong squeeze makes the plug not easy to fall off, effectively reducing the occurrence of non-human factor power failure. At the same time, the socket clamp piece using high-quality tin phosphorus bronze, good conductivity, fatigue resistance, to protect the socket insertion and extraction times up to 10,000 times (the national standard is 5,000 times).
What are the good quality brands of leakage switches and how to buy switches in these two areas of knowledge, we have done a detailed introduction, I do not know whether you are satisfied with our above introduction? We hope that this article about the switch can let you better understand the switch, buy switch.
