This is small helpful idea.
I live in town and positions of light switches are in 1.5m.
When my children say: "taddy I need light in kitchen; I need light in bath....."
That’s why I construct switches like on photos. My childen are very happy and "boogieman" in past.
To do this simplest switch you’ll need
1. Switch for table lamp (1$)
2. 1m of 2 wire cable (0.2-0.5$)
I spend 4.5$ for 3 switches and quest completed and 30 minutes of time.
note, that for moving 3 switches down with drilling holes in ferroconcrete, repairing walls, and etc you’ll spend 100+$
If someone needs more detailed photos with wire connection - I’ll make it for you.
