1, the surface technology, a good product smooth surface, smooth color, texture, brand identity clear and full.
The screw wire type wiring is tight, and it is suitable for multi-wire parallel connection with different wire diameters. The electricians are more accustomed to the traditional wiring methods and are used by most manufacturers, but the brand products are adopted in how to increase the contact area of screws and wires and reduce the damage of wires. With certain improvements, the copper screw heads have a circular arc design and are equipped with anti-screw off structures.
The quick wiring method is mainly to use a combination of multiple spring plates to press the wire. The characteristics of the construction speed is fast, the line is not afraid of rotation, and multiple lines are difficult to be connected in parallel.
The nail board pressure line method is a new wiring method that appeared after 2006. The main function of the wiring is basically the same as that of a miniature circuit breaker, but it takes up more space in the rear seat.
The switch, as the name suggests, is an appliance that has both opening and closing functions. Therefore, it is difficult to guarantee the quality of such switches. It is recommended that you buy less.
The switch of the sterling silver contact, when turning on or off the large current load, is prone to pull arc, the surface of the contact will be burned by the arc, and the pure silver itself is easily oxidized. Silver alloys mainly include silver-lithium alloys, silver-cadmium alloys, and silver-nickel alloys, among which the overall performances such as electrical conductivity, wear resistance, and arc reduction are preferably silver-nickel alloys, followed by silver-silver alloys, silver-cadmium alloys, but cadmium Heavy metals, toxic to the human body and the environment. Material is to look at the contact material. The contact is the contact point of the conductive part during the switching process.
2, internal materials:
The brand switch should use silver alloy for contacts and tin-phosphorus bronze composite materials for conductive bridges.
Most of the rear seat materials of good products are made of nylon 66 color and fire retardant materials. Switch sockets made by ABS are generally used in some newly-developed commercial housing and are not suitable for home decoration. Although ABS has a certain surface hardness, it has poor impact resistance and flame retardancy, and it is easily oxidized and discolored. The surface will appear yellowish soon after use. It is also the main material for domestic production of switch sockets before the 1990s and is mainly used for the production of bottom boxes. It is a kind of thermoplastic engineering plastics with excellent overall performance. It has the advantages of high strength, high toughness, high heat resistance, high flame retardancy, high electrical insulation, UV resistance, color stability, and discoloration. It is widely used in automobiles, electrical and electronic, Construction, office equipment, packaging, sports equipment, health care appliances, household products and other fields.
Polycarbonate referred to as PC material, commonly known as bulletproof plastic. The panel materials on the market include polycarbonate, urea resin (electric jade powder) and ABS engineering plastics. Switch sockets control the safety and convenience of electricity in our lives. An electrical switch is an electrical accessory that connects a current and a cut-off current; a socket is responsible for the connection of an electrical plug and a power supply.
