The method i have been taught for 2 way/intermediate lighting is to have a switch line (twin and earth) and a length of three core connected to a 2 way switch, then a length of three core to an intermediate switch, and finally a length of three core to a second 2 way switch. Does it matter as to which of the three switches that the switch line is connected? Ie, can it be connected to the intermediate? Many diagrams show the switch line connected to the first 2 way switch.
Secondly, do 2 gang switches with separate 2 way and intermediate switch exist?
