The installation position of the switch is convenient for operation. The distance between the switch edge and the door frame edge is 0. 15 ~ 0.2m, the switch height from the ground is 1.3m, the cable switch height from the ground is 2 ~ 3m, and the height from the ground is less than 3m. When the distance between the cable switch and the top plate is not less than 100mm, the cable outlet is vertical downward.
The same model is installed side by side, and the same indoor switch is installed at the same height, with orderly control and good position. The adjacent spacing of parallel-installed cable switches shall not be less than 20mm. The concealed switch panel should be close to the wall, with no gaps around, firm installation, smooth surface and no chipping and scratches.
Extended data
1, the installation height of the socket shall be installed according to the design requirements when specified in the design; When the design is not clear, the following requirements should be met: the socket with safety door should not be less than 0.3M；; The outlet without safety door shall not be less than1.8m. It is recommended to buy the outlet with safety door as much as possible, because the price difference between them is not big.
2. Bathrooms or other damp places should use well-sealed waterproof and splash-proof sockets. Three hole socket, when inserting the plug, first insert the grounding pile head (slightly longer) into the hole, and the mechanism in the socket opens the other two hole doors. The two-hole socket must be inserted into the socket pile head at the same time before the safety door can be opened, so as to prevent children from inserting metal objects by mistake and causing safety accidents. )
3. When the socket is installed, its panel should be straight and close to the wall. Moreover, the wiring (phase) should conform to: single-phase two-hole socket, the right hole or upper hole facing the socket is connected with the phase line (live wire), and the left hole or lower hole is connected with the zero line; Single-phase three hole socket, the right hole facing the socket is connected with the phase wire (L, live wire), the left hole is connected with the neutral wire (N), and the upper hole is connected with the ground wire (PE).
