To use Canique Switch, you need to connect at minimum:

VCC - connect to a power supply 2.25-3.15V
GND - connect to GND of power supply
SET - connect to a microcontroller or drive manually
RST - connect to a microcontroller or drive manually
ZZ - connect to a microcontroller or drive manually

(SET/RST/ZZ are relative to GND.)

AC Load

For an AC load that you want to switch on/off, you need to connect:

L (Live) - connect this to the live (L) wire of your AC supply
NO (Normally open) / NC (Normally closed) - connect one of them to your load. The NO/NC output is either internally disconnected or internally connected to the wire that you attached to L depending on the relay state. NO means if the relay is off, NO has no connection to L, and gets connected to L as soon as the relay switches on. NC is the exact opposite of NO.

For examply, usually you'd connect a LED light bulb to NO.

Connect the N (Neutral) wire of your load directly to the N wire of your AC supply.

DC Load

For a DC load that you want to switch, you need to connect:

L (Live) - connect this to the VCC of your DC power supply (max 220V DC)
NO (Normally open) / NC (Normally closed) - connect one of them to the positive input of your load.

Connect the GND of your load directly to the GND of your DC power supply.

1. Drive ZZ high (to volage of VCC, e.g. 3V)
2. Drive SET high, drive RST low
3. Wait for ~10ms
4. Drive ZZ, SET, RST low or disconnect them (high impedance).
5. If you want you can also disconnect VCC/GND. The relay will keep its turned on state.
