As we all noted that the market has emerged a variety of brands,but how us to choose and installation the right switch socket. so that when everyone chooses do not know how to start, choose a suitable switch socket is still very important in a family . The following Xiao Bian will introduce to you how to install the three control switch and how to distinguish the quality of the switch socket.
How to install the three control switch
1, first of all to prepare three switches, generally like two open dual control switch, a double open dual control switch, while also preparing a number of wires;
2. When the FireWire is connected, it is necessary to connect a single control switch L so that it can lead to the control lines L1, L2;
L1 led L1 connection dual control switch, L2 L2 connected dual control switch;
3. The L1 on the left side of the dual control switch is connected to the right switch L2 and L2 is connected to L1;
4, lead out of the dual control switch L, the next step is to connect it to the third single control switch L1, L2;
5, then led to the third single control switch L to the lamp holder, lamp holder another line to connect the zero line, so that the three control lines will be connected well.
How to distinguish between switch socket and socket
1, choose the switch brand
Try to buy high-quality sockets that have passed the test of time and market. For example, the brand of CHINT switch socket that we often use is its raw material selection through research and development. This product is a complete and strict quality assurance system.
2, see the switch socket material
If you choose a good switch socket panel materials used are flame retardant, insulation, impact resistance, etc. It can be said that it is in the technical indicators are subject to national standards.
3, the switch socket shell material is many, for example, like Germany Bayer's pc is relatively good, flame-retardant high temperature. Then you can use a lighter to test whether it can be flame-retardant or heat-resistant.
4, see the socket conductor material
A good socket brand uses phosphor bronze. Tin-phosphorus bronze sheet has good elasticity, anti-fatigue, and is not easy to oxidize. High-precision tin-phosphor bronze has good electrical conductivity and elasticity, so that the material can effectively ensure the passage of large currents. The integrated phosphor bronze has higher precision and better quality.
5, see switch socket whether there is security
Sockets with security door design, if there is such a design can effectively prevent the baby in the home accidentally plugged in electric shock, but also greatly enhance the security of the socket. It also prevents pests and dust from entering. You can find a key that is just enough to insert into the hole and forcefully insert it into the single hole. If you can't easily break through the barrier of the protection door, you can actually protect the safety of your family.
6, see the socket pitch distance
The hole pitch of 15mm is already a reasonable spacing of the general household five-hole socket, if 19mm this can easily cope with various special plugs, the practicality is relatively high.
Finnally we need install the three control switches and how to distinguish between the quality of the switch socket is introduced to this, three control switch installation should pay attention to the details of the part, no matter what kind of switch, select the reference to the above points, so that the product It will be safer to use.
