Ajax LightCore 2-Way Smart Light Switch Core
R1,249.00 Incl. VAT
The Ajax LightCore 2-Way Jeweller is the electronic switching core for controlling one lighting circuit from two switch positions without requiring a neutral wire. Add a SoloButton 1-Gang touch panel to complete each Ajax switch point.
- Controls one lighting circuit from two switch positions
- Supports lighting loads from 5 W up to 600 W
- Operates from the live phase without requiring a neutral wire
- Supports manual switching, Ajax app control, schedules and automation scenarios when connected to a compatible Ajax hub
- Built-in current and temperature protection helps protect the switch and connected load
SoloButton 1-Gang is required. Installation into a standard South African 100 × 50 mm / 4 × 2 wall box also requires an IoT 4 × 2 Wall Box Installation Adapter.
Description
Ajax LightCore 2-Way Smart Two-Way Switching Core for One Lighting Circuit | 83429.142.NC
The Ajax LightCore 2-Way Jeweller is the electronic relay used when one lighting circuit needs to be controlled from more than one switch position. It is ideal for staircases, passages, bedrooms and larger rooms where the same light needs to be switched from two locations.
This is a 2-way switch rather than a 2-gang switch: it controls one lighting circuit from multiple switch positions, not two independent lighting circuits. The LightCore operates without a neutral wire and is completed with an Ajax SoloButton 1-Gang touch panel.
Complete Your Switch
The LightCore is the switching relay only. The components required depend on how your 2-way lighting circuit is being configured:
| Component | Purpose |
|---|---|
| Ajax LightCore 2-Way | The electronic relay for one Ajax 2-way switch position |
| Ajax SoloButton 1-Gang | Required touch-sensitive front panel for each Ajax LightCore 2-Way, available in Black or White |
| Second 2-way switch point | Use another Ajax LightCore 2-Way with SoloButton 1-Gang, or a compatible conventional mechanical 2-way switch |
| IoT 4 × 2 Wall Box Installation Adapter | Required at each Ajax switch position installed into a standard South African 100 × 50 mm / 4 × 2 wall box |
If you already have the required second switch point and a compatible SoloButton 1-Gang, the LightCore can be purchased on its own. Otherwise, choose the required touch panel and wall-box adapter using the Product Add-ons on this page.
How It Works
A 2-way lighting circuit allows the same light to be switched from two different locations. The Ajax LightCore 2-Way can operate with another LightCore 2-Way or with a compatible conventional mechanical 2-way switch, allowing an existing 2-way lighting arrangement to be upgraded without requiring a neutral conductor at the Ajax switch position.
A SoloButton 1-Gang attaches to the LightCore to provide the touch-sensitive control surface. The touch panel also contains the antennas used for communication with the Ajax hub, so it must be installed before the LightSwitch is added to the Ajax system.
Once assembled, the switch can operate locally without being added to an Ajax hub. Connecting it to a compatible Ajax system adds remote app control, schedules, timers and automation scenarios.
Why Choose This Product?
- Control one light from two locations: ideal for staircases, hallways and rooms with more than one entrance.
- No neutral required: useful for retrofit installations where a neutral conductor is not available at the existing switch position.
- 5–600 W lighting control: supports a wide range of compatible LED, incandescent, halogen and conventional fluorescent lighting.
- Touch and contactless control: with the correct touch panel fitted, the switch responds to touch or a hand approaching within approximately 15 mm.
- Smart and local operation: use the completed switch normally at the wall or control it remotely through Ajax apps when connected to a compatible hub.
- Automation ready: use schedules, timers and Ajax scenarios to control lighting according to time, security status or other supported system events.
- Built-in protection: current and temperature protection can disconnect the connected load when operating limits are exceeded.
Before You Buy
- This product is the LightCore 2-Way relay core only. An Ajax SoloButton 1-Gang touch panel is required to complete each standalone Ajax switch point.
- 2-way refers to controlling one lighting circuit from more than one switch position. It does not control two separate lighting circuits.
- A complete two-location circuit requires a suitable second 2-way switch point. This can be another Ajax LightCore 2-Way or a compatible conventional mechanical 2-way switch.
- For each Ajax LightSwitch installed into a standard South African 100 × 50 mm / 4 × 2 wall box, add an IoT 4 × 2 Wall Box Installation Adapter.
- The Ajax LightSwitch uses the European type 55 mounting format and does not fit directly into a standard South African 4 × 2 wall box.
- A compatible Ajax hub is required for remote app control, schedules and automation, but local switching can operate without a hub once the LightSwitch is correctly assembled.
- For a low-power or unstable lighting load, the bundled capacitor may need to be connected in parallel with the lighting appliance.
- Smart lamps containing their own brightness or colour control, relay, radio module or microcontroller are not supported.
- The LightCore is rated IP20 and is intended for indoor installation.
- Installation must be carried out by a suitably qualified electrician or installer.
