The average bed height is 40 cm, and the mattress is 10---15 cm, and the switch at 50 cm should be suitable.
Normally, it is about 70 cm above the ground. But as soon as you move it higher than the bedside table, it's about 10 centimeters. Electricians know it.
The standard size of the bedside table is roughly the unit proposed by the national light industry department: width: 400 mm-600 mm, depth: 350 mm-450 mm, height: 500 mm-700 mm.
Bedside table socket height: between 70-80cm. Higher than the bedside table, lower than the bedside, the bedside table height is generally 55-58, so the socket position is set at 10cm higher than the bedside table, if it is a lamp switch, of course, and the socket is separated, the switch position of the lamp is 1 meter, the socket is 30 cm above the ground, so as to be installed 5 to 10 cm above the bedside table, so that the wall is inside, do the socket with a safety switch, so that it is safer. >>>More

The standard distance of the power socket from the ground is 30 cm, but in special places, the height can be appropriately modified according to your own convenience.
