How to connect the terminals of the Single Switch Module T1 (No Neutral)?
There are 5 wiring terminals on the back, which are L, L1, S0, S1 and N. Among them, the phase wire connects to L; the lighting connects on to L1.
There are three connection methods for S0 and S1:
1. Connect them to both ends of the external switch respectively;
2. Connect S0 to one end of the external switch; S1 is inactive. The other end is connected to the phase;
3. If there is no external switch, you don't need to connect it.
The first two connection methods allow control of the module by the external switch.
