Retrotouch Crystal Touch Switches (2-way and intermediate) pairing

Retrotouch Crystal Touch Switches (2-way and intermediate) pairing

Retrotouch Crystal Touch Switches make installing 2-Way and Intermediate (Multi-Way) lighting circuits straightforward. Instead of routing complex traditional mechanical strapper wires, Retrotouch switches utilize a digital Live Link terminal system. 

1: Physical Wiring 

Before beginning the pairing sequence, the hardware units must be wired correctly

2 way and intermediate configurations rely on one Master Switch (which physically controls and connects to the light fixtures) and one or more Slave/Secondary Switches (which receive power and communicate via the link line, but do not wire directly to the light). 

Live (L) : Connect your permanent mains Live supply feeds directly into the corresponding L  terminals on both the Master and the Slave switch units

Switched Live (L1 / L2 / L3): Connect the load wire running directly to your lighting circuit only into the designated Load terminal of the Master Switch.  The load terminals on all Slave units must remain empty 

The Link Terminal: Connect a core wire directly between the Link terminals of both switches  This line carries the digital Live communication pulses between the panels.


2: The Pairing Process

Once the physical wiring is completed and the glass faceplates are securely clicked on, turn the mains power back on. Allow 2 minutes for the touch sensors to automatically calibrate their baseline proximity registers before attempting to touch the panels


1. Activate Master Pairing Mode:

Go to the physically wired Master switch (the one connected to the light load)

Press and hold your finger firmly on the specific touch gang/button area you want to sync for 5 seconds until its backlit background LED indicator light begins to flash.

2. Link the Slave Switch:

Within 60 seconds of the Master switch beginning to flash, walk over to your Slave/Secondary switch

Press the corresponding touch gang/button area on that secondary panel

The unit will flash or emit an audible click to confirm that the Master/Slave relationship link is successful

3. Repeat for Multi-Gang Layouts:

Complete for multi-gang setups. If you are configuring a 2-Gang or intermediate setup, repeat this process individually for each separate light circuit gang you wish to pair.



3: Factory Reset (Unpairing)

If you pair the wrong buttons together, change your room layout, or need to clear a Slave switch from a multi-way circuit, you must wipe the switch's local memory
.

How to Reset Standard (Non-Wi-Fi) Touch Switches:

  1. Isolate the mains power to the switch circuit at your central consumer unit/fuse box
    .

  2. Press and hold your finger firmly down on the active touch button area
    .

  3. While keeping your finger firmly held down, turn the mains power breaker back ON.

  4. Watch the backlit background LED indicators closely. The switch will begin to flash Blue.

  5. The exact moment it begins flashing blue, let go of the touch area immediately, and then press and hold it down a second time.

  6. Continue holding until you hear an internal mechanical click and the background indicator light turns off completely.

The switch memory is now wiped clean. Let the switch sit completely untouched for 2 minutes to allow the proximity sensor baseline to recalibrate safely before operation.


Troubleshooting

  • The Slave switch fails to beep or flash during Step 2: Ensure you press the Slave button within the 60-second pairing window
    . If the Master unit stops flashing before you complete the step, the pairing mode has timed out and you must start Phase 2 over
    .

  • The light switches turn on from the Master but won't turn off from the Slave: Verify your Link terminal wiring. If the communication wire is loose or disconnected, the digital syncing pulse cannot travel between the units
    .

  • The switches act independently but refuse to sync: Ensure you have not accidentally wired the switched live light load to both switch bases. The light load wire must connect exclusively to the designated Master switch unit
    . Slave switches only require Live, Neutral, and the Link connection line.
