Connection scheme for spotlights and sconces in the corridor
There are 2 keys. One includes both point and 4 sconces, the second rest sconces, but only when the first key is turned on. It doesn’t work separately. The question is whether it is possible to make one turn on these two sconces, regardless of the first, or does one key include only point sconces, the second only sconces. So that the walls are intact?
In a word, the fever of a drunken crazy electrician. Although it may be the ideologist of this scheme.
The correct connection diagram is described here. https://our.electricianexp.com/en/elektricheskaya-sxema-podklyucheniya-dvuxklavishnogo-vyklyuchatelya.html
