How can I accurately wire the smart light switches for proper connection?

Follow the wiring diagram below to connect the wires successfully.

  1. Singapore wall switches do not use neutral wires in general except for water heater switches because the neutral wires are linked from one lighting fixture to the next and back to the distribution box. 

  2. Lin is the Live incoming wire that provides the electricity needed to power the lighting fixture. Lin is also known as COM (COMMON) or L or Live.

  3. L1 / L2 / L3 are the lighting points. In a 1-gang switch, there will only be an L1. There will be an additional L2 & L3 for the 2 & 3 gang switches respectively.
