Hi, I am currently rewirering my house and installing dimmer 2's and rgbw's. I bought a load or MK grid switches so I could have momentary on/off's at the top, rocking switches in the middle and scenes below. The scenes and rockers will be connected to my raspberry pi's. My electrician has pointed out that there needs to be physical segregation between data cables and 240v within the back box. He says its to do with the possibility that one of the 240v cables could make one of the data cables live if someone where to do something wrong. I understand the risks of electromagnetic interference, but this is separate to that issue. So If I install the system using momentary switches from the dimmer 2's will there be any 240v in the switch. To make my question clear what voltage and current is the S1 and Sx circuit when the dimmer is used in momentary mode? If they are low voltage I could fit them outside the grid back box. I know the RGBW's are elv so they shouldn't be a problem. Many thanks for reading
