The North American smart home market is experiencing remarkable growth, with smart lighting leading the charge. According to the Research and Markets report1, the NA smart lighting market is projected to reach $22.9 billion by 2032. That’s not just a tech trend — it’s a shift in how people interact with their homes. Consumers aren’t just looking for bulbs that turn on and off; they want lighting that adapts to their lives. Smart lighting that can be controlled remotely and adjusted automatically based on daily routines is becoming the norm.
It is a prime opportunity for industry professionals to deliver advanced, easy-to-install solutions that meet users’ demands. So meet the LightSwitch [120] Jeweller series that includes smart touch switches designed for seamless lighting control and automation, specifically for the North American market.
The series consists of three switches:
LightSwitch (1-gang) [120] Jeweller for controlling a light source from one spot Already available for order |
LightSwitch (3-way) [120] Jeweller for controlling a light source from two spots Will be available to order in Q2 2025 |
LightSwitch (4-way) [120] Jeweller for controlling a light source from three or more spots Will be available to order in Q3 2025 |
Comfort and security with one touch
LightSwitch is a convenient device for controlling one or more light sources manually or using the Ajax app. The new switches respond even to light touches. Moreover, it is enough just to approach a hand, elbow, knee, or any part of the body close to LightSwitch — and it will respond without physical contact. High-quality sensors prevent accidental activation and ensure the light switch responds only when needed. Additionally, the soft backlight makes it easy to find the switch in the dark.

A single switch can control all the switches in a facility, so a single tap in an Ajax app can turn on/off the light in a large office or warehouse. Yet, LightSwitch not only makes it easy to control the lights but also provides a variety of automation scenarios that enhance a security system. For example, the switches can turn the light on/off by schedule to simulate an owner’s presence or turn the light on in response to a fire alarm to facilitate evacuation.
The Ajax apps provide real-time informative notifications and an event log, enabling users to monitor any changes remotely. A control screen is always at hand. Make sure all the lights are off even being far away from home or an office.
Automated light control
With Ajax smart switches, lighting automation scenarios are numerous. The switches can be automatically activated by arming/disarming an Ajax security system or when any device in the system, for example, an opening detector or motion detector, is triggered. This way, the lights might deter an intruder.

The light will significantly reduce the risk of system sabotage
Also, any LightSwitch can be used to activate other Ajax devices. The switch can control Socket Jeweller, WaterStop Jeweller, Relay Jeweller, or WallSwitch Jeweller to automate routine actions.
Use LightSwitch to turn off the lights and simultaneously lower roller shutters. Situations like a homeowner or office worker forgetting to close a roller shutter are now excluded. Just set up an automation scenario for the relay that controls roller shutters. Add LightSwitch and Relay Jeweller to the Ajax hub via the app. Then, in the Scenarios menu, select By switch actuating so that when LightSwitch turns off, it automatically sends a command to the relay to lower the shutters.
Automation scenarios are executed on the hub level, so they will keep running even without a connection with the server. All automation scenarios are configured in the Ajax apps. Whichever automation scenario is used, it is executed in less than a second and recorded in the event log.
Designed for any interior
Design-wise, all LightSwitch [120] Jeweller models seamlessly integrate into any environment, whether a cozy home, a sleek high-tech office, or an industrial setting. With an eight-color palette, switches offer the flexibility to make a bold design statement or blend the devices seamlessly with the interior.

Assemble a switch to suit specific needs
Ajax light switches are prefabricated devices. A different set of components is required depending on whether a light switch is used as a single device or in combination with other light switches.
A single LightSwitch consists of a LightCore relay and a touch panel. A plastic Frame with the appropriate number of seats is used to install two or more switches together:

It is quite easy to assemble the device thanks to the light switch configurator. Use this web tool to combine devices into a frame, pick the color, and download the configuration as a convenient PDF file.
Quick and easy installation
LightSwitch [120] Jeweller series is designed to bring smart lighting control with ease. These new switches can replace existing ones without requiring new wiring. The devices feature a form factor that aligns with the typical dimensions of NA mounting boxes. They also do not require a neutral wire.

LightSwitch [120] Jeweller series is rated for light bulbs up to 500 W, making it compatible compatible with a wide range of lighting fixtures, from dim bedside lamps to bright ceiling lights.
Light that never fails
Devices of the LightSwitch [120] Jeweller series are free from concerns related to Wi-Fi, Z-Wave, ZigBee, or Bluetooth connectivity. Instead, they use Jeweller — a proprietary two-way radio communication protocol. Jeweller technology is stable and ensures continuous device operation without sudden disconnections.
Jeweller protocol transmits data between the light switches and the Ajax hub over a distance of up to 3,600 ft. This is, on average, longer than competing solutions can provide. The hub can be connected to up to four internet providers simultaneously via Ethernet, Wi-Fi, or two 2G/3G/LTE cellular networks.

The number of available communication channels depends on a hub model
Embrace the convenience of Ajax smart switches
LightSwitch [120] Jeweller series transforms the way users interact with their environments. Both PROs and end users can look forward to a new era of home automation that combines a thoughtful user experience with the reliability of professional security systems.
