Wiring diagram:

• N: Connect the neutral wire of the power supply.
• The control wires for open, stop, and close are marked on the corresponding pins.

Step 2: Install the switch in the recessed box.

• Remove the switch glass: Use a screwdriver to insert into the small groove on the switch bezel and gently push to remove the glass.
• Install the switch in the recessed box and reinstall the glass.

Note:

• Compress the electrical wires in the recessed box to fit the switch and avoid screwing into the wires.
• Do not screw too tightly, as this will bend the switch, warp the switch’s touch circuit, and prevent the switch from being turned on or off manually.
