Ajax LightCore LightSwitch Relay, 1-Gang, No Neutral, Jeweller, LIGHTCORE-1-GANG

Introduction: Ajax LightCore LightSwitch Relay (1-Gang) — What it is and who it is for

The Ajax LightCore LightSwitch Relay 1-Gang (LIGHTCORE-1-GANG) is a compact smart switch relay designed to add remote, automated and secure control to conventional lighting circuits. Built to work within the Ajax ecosystem via the Jeweller two-way radio protocol, the module installs inside a standard European 55-type mounting box and enables contactless control through separate LightSwitch touch panels or buttons. Its standout characteristics include operation without a neutral conductor, a long radio range, built-in protections and compatibility with multiple Ajax hubs and ReX extenders — making it attractive for retrofit projects, new smart-home installs and commercial environments where tidy, discreet relay integration is required.

Key features at a glance

• No neutral required:powers from the live phase only, ideal for older wiring without a neutral in the switch box.
• Jeweller radio protocol:reliable two-way communication with Ajax hubs, open-space range up to ~1,100 m (region dependent).
• Contactless touch activation:touch panels operate through a ~15 mm distance and offer optional soft backlighting.
• Load capacity:supports up to 600 W for the 1-gang variant with overcurrent and overtemperature protection.
• Compact design:fits standard European 55-type mounting boxes for a discreet modular installation.

Detailed specifications and benefits

Understanding the technical details helps clarify where this relay excels and how it will perform in real installations.

• Protocol: Jeweller two-way radio — designed for low-latency, secure communications within the Ajax security/smart-home ecosystem.
• Compatible with: Hub Plus, Hub 2, Hub 2 Plus, Hub Hybrid and ReX range extenders. The relay requires a separate LightSwitch touch panel or button to initiate local touch control.
• Benefit: Tight integration with Ajax hubs allows you to combine lighting control with alarm, automation and scene logic, keeping everything manageable from the Ajax app.

• Frequency bands: region dependent, covering typical ISM bands used in Europe, the UK and select international markets.
• Range: up to 1,100 m in open space (real-world range will be lower indoors but is extended significantly with ReX extenders).
• Benefit: long, reliable range reduces the need for additional wiring or repeaters in medium-sized properties when paired with suitable hubs or extenders.

• Supply: 230 V AC, 50/60 Hz — no neutral required; ideal for retrofit situations.
• Maximum switched power: up to 600 W for 1-gang models (300 W per segment on 2-gang variants).
• Current protection: device turns off and sends a notification if current exceeds ~2.6 A; overtemperature protection triggers above +60 °C.
• Benefit: safety features reduce the risk of overload and overheating, supporting long-term, unattended operation in home and commercial settings.

• Dimensions: 76.3 × 72.3 × 29.2 mm; weight ≈ 46 g — compact enough to fit behind switches in standard 55-type boxes.
• IP rating: IP20 — intended for indoor use only.
• Operating conditions: −10 °C to +40 °C, up to 75% non-condensing humidity.
• Compliance: consult the official datasheet and product page for CE/UKCA and regional approvals.

Practical benefits in everyday use

• Retrofit-friendly: because it does not require a neutral conductor, the LightCore relay is often the simplest way to add smart control to older homes with two-wire switch loops.
• Discrete installation: the relay hides behind the switch or inside the wall box, preserving decor and allowing modern touch panels to be used without bulky devices on view.
• Reliable ecosystem integration: pairing with Ajax hubs brings the relay into a wider security and automation system — lighting can react to alarms, schedules or presence detection.
• Robust protections: overcurrent and thermal cutoffs protect wiring and loads, and the module reports fault conditions to the hub/app for quick troubleshooting.

Use cases and ideal scenarios

The LIGHTCORE-1-GANG relay is especially well suited to several common scenarios:

• Heritage and retrofit homes:older buildings frequently lack a neutral in the switch box. This relay offers a simple way to add smart lighting without pulling new conductors.
• Multi-room automation:when used with Ajax hubs and ReX extenders, lights can be centrally scheduled, grouped into scenes or linked to security events (e.g., lights on when an alarm is triggered).
• Commercial fit-outs:small offices, cafés or boutique retail spaces can use concealed relays to maintain clean aesthetics while offering app control, energy schedules and central management.
• Security-aware installations:because the relay is part of the Ajax family, lighting can be integrated into alarm responses, giving you automated visual deterrents or safe-route illumination in emergencies.

How it compares to similar products

It helps to compare the LightCore LightSwitch relay with other smart relay options to understand trade-offs.

Many smart relays (and smart switches) require a neutral conductor to power the module. The LightCore 1-Gang stands out because it operates from live only, making it much easier to install in homes without rewiring. The trade-off with no-neutral designs can be reduced compatibility with certain low-wattage LED loads; however, Ajax mitigates that with minimum load guidance and protective cutoffs.

Wi-Fi based relays are common and inexpensive, but they can suffer from latency, local network dependence and coverage issues. The LightCore uses Ajax Jeweller — a purpose-built, two-way radio optimized for smart security and home control — offering lower latency, better range and a design focused on reliability and battery-awareness in the wider Ajax system. If you already use Ajax for security, the LightCore provides tighter, more secure integration than a generic Wi-Fi relay.

The LightCore sits between consumer DIY relays and professional automation hardware. Its design focuses on secure operation and professional installation (installation by a qualified electrician is required), which may appeal to installers and property managers who prioritise safety, compliance and ecosystem integration over the lowest possible price.

Conclusion: Why choose the Ajax LightCore LightSwitch Relay 1-Gang?

For homeowners, installers and small businesses seeking a discreet, reliable smart relay that integrates with a security-conscious smart-home ecosystem, the Ajax LightCore LightSwitch 1-Gang is a compelling choice. Its ability to operate without a neutral makes it an excellent retrofit solution, while Jeweller radio and Ajax hub compatibility ensure dependable control and automation. Built-in protections, compact dimensions and professional-grade installation expectations make it suitable for installations where safety and compliance matter. If you prioritise clean aesthetics, secure integration with an alarm and automation platform, and a product designed for installers rather than a consumer plug-and-play device, the LIGHTCORE-1-GANG is worth considering.
