The 1. switch does not control the socket, but two switches can control two electrical appliances, as shown in the following figure:
2. One switch can control the socket, and the other switch can control all the electrical equipment, as shown in the following figure:
Second, the wiring matters needing attention:
1. When wiring, be sure to pay attention to the safety of electricity and wire according to the specifications;
2. It is forbidden to connect wires in a virtual way, with reasonable wire layout and correct connection;
Red is the fire line, blue is the zero line, and yellow is the ground line.
Extended data:
Selection of switch
First, the eye view:
Generally, good products are flat, burr-free, bright in color, and made of high-quality abs+PC, which has good flame retardancy and is not fragile. Although the surface of some products is bright and clean, it seems to be coated with oil, but the color is very light and the texture is very thick. This material has poor flame retardancy. You can ignite it with fire to try its flame retardancy. If it goes out soon, it is good plastic, otherwise it is poor plastic.
Second, the hand press:
A good product panel will not be taken off directly by hand, and certain special tools must be used. Generally, the lower cover of non-mainstream middle and low-grade products can be easily taken off by hand, which will make the home and public places indecent. When choosing, press the cover diagonally with your index finger and thumb to form an endpoint, keep one end still and press the other end hard. If the cover is loose and sunken, the product quality is poor, otherwise the quality is reliable.
Third, listening:
Gently press the switch function, the lighter the sound of the skateboard, the smoother the feel and the better the quality; On the contrary, the sound is impure and dynamic when opening and closing, and the sound quality with intermittent state in the middle is poor.
Fourth, look at the structure: there are two general switch structures:
1, skateboard type and pendulum type. Skateboard switch, pure voice, elegant and comfortable; The pendulum structure has clear sound and low metal impact sound, which is more stable and mature than the traditional skateboard structure in arc extinguishing and service life.
2. Double-hole pressure plate wiring is safer than screw wire pressing.
Because the former increases the contact area between wires and electrical appliances, it is oxidation-resistant, not easy to loosen and have poor contact. When the latter screw is strong, it is easy to crush the wire, and the contact area is small, which makes the electrical parts easy to oxidize and age, leading to poor contact.
Verb (abbreviation of verb) material comparison:?
1, switch pure silver has strong conductivity, low calorific value and high safety performance, and the performance is greatly reduced when the contact is made of copper; The socket is made of tin-phosphorus-green copper sheet, which can get the best strength, toughness, elasticity and other indicators, and it is tens of times more durable than the socket with ordinary brass reed, and the socket is rarely burned by strong arc when inserting the board.
2. The gold-plated spring needle is extremely difficult to oxidize and has stable performance, which can ensure clear and true sound quality and fast and accurate data transmission.
