1.The difference between single control switch and dual control
Single control switches are ordinary switches. The dual-control switch is to use two dual-control switches to control one lamp. For example, the stairwell generally uses the dual-connected dual-control switches to control the lamps on this floor and the upper or lower floors. Duplex buildings or larger rooms are also often used.
2. What does the protective door on the socket mean?
Generally, the socket of the wall socket panel has a safety cover inside. When the plug is plugged in, the protective cover will automatically turn up, and the plug socket will be closed automatically when the plug is removed. It is mainly to prevent small children from jamming their fingers.
3. Is the switch panel a GM back box of the same model?
At present, the bottom box is mainly divided into type 86 and type 118. The size of the type 86 bottom box is 86mm × 86mm. Generally, the type 86 is used in households, but some areas such as Sichuan, Xi'an, Wuhan and other cities generally use type 118. If you are not sure which one to use, it is best to consult an electrician before buying. Different types of 86-type switches can use 86-type bottom boxes. The bottom boxes are standard and can be used between different brands.
4. Is there a waterproof switch for home use?
For general switches, add a waterproof cover to the outside of the switch. This also greatly enhances security.
There are two types of waterproof cover: switch and socket. Please pay attention to the distinction before purchasing.
5. Can a five-hole socket be inserted into two and three holes at the same time?
This is not all five-hole sockets can be inserted simultaneously two and three holes. Mainly look at the distance between the two holes and three holes. The distance between the holes of the Siemens Vision series is slightly smaller. If the plug is relatively thick, two and three holes cannot be inserted at the same time; the five holes of ABB are misaligned, which solves this problem well.
