Hi, I just bought a light broadlink TC1 light switch to try out. When I opened my switch, I see 3 red wires. 2 of them connected together and 1 by itself. I can't tell which wire is Live, load or neutral [Do hdb switch have neutral wire?]. Can anyone kindly guide me on how to connect? Any help would be deeply appreciated. Update: Nevermind, found out which is which and its working now.
