In-Wall Switch

Question: I need to replace a 3 way switch with the smart in wall switch but can’t find directions on how to do the install. Can you please send them?


There are two solutions to use YoLink In-wall Switch to replace a Three-way Switch.

Solution 1, Use one YoLink In-wall Switch as the light control and another YoLink In-wall Switch as the mutual control device.

1) Use a YoLink In-wall Switch as the lamp switch (switch A), you can directly control the lamp on/off.

2) Use one or more YoLink In-wall Switches to connect to the power supply only, create a pairing relationship with switch A, and act as a control device for switch A (only as a control device). About how to create a pairing relationship between YoLink In-wall Switches, please find it in the following user guide on Page 23 – Pairing.


Solution 2, Use a traveler line to connect two YoLink In-Wall Switches together through Live terminal.

1) Use a YoLink In-wall Switch to connect directly to the lamp

2) Use one or more YoLink In-wall Switches to connect the live terminal through the traveler line, each YoLink In-wall Switch needs to be connected to the neutral line.

And please kindly refer to the installation part (P8-13) on the following user guide before install.



Question: I have no neutral wire, will the in-wall switch work?


Really sorry the YoLink In-wall switch needs neutral wire for installation.
YoLink In-wall Switch is a zero fire switch, it can be used only with neutral input and live input.
As for a single fire switch with Hot Line only, no Neutral line, our product is not applicable.


Question: Can these be used with two, three and four gang wall plates ? That is the current setup I have in my place.


Yes, YoLink Smart In-Wall Light Switch can be used with two, three, and four gang wall plates.

Please kindly note:

  1. The maximum resistive load of YoLink Switch is 10A/110V.
  2. YoLink Switch is a single-bit switch. If you use it to replace a multi-gang switch, the original multiple switch button control will become a switch button control, and no longer supports single button control by region
  3. The multi-gang switch has multiple wiring harnesses connected to the lamp. Replaced by YoLink Switch, the multiple wiring harnesses need to be connected to one terminal at the same time. The standard specifications of the wire (the wire that can pass 10A current) may not fit into the screw together.


Question: How about the in wall switch, does it works on 230V mains?


The working voltage for YoLink In-Wall Switch is 100-240V AC.


Question: Will you ever come out with a Dimmer Switch device?


We have taken the dimmer light to our road map. It will be released next year.


Question: Is that the YS5705-UC will only perform as a programmable timer?
