ABB Inora 1 Gang 10AX Intermediate Switch Royal Gold BL119-PG

The 10AX designation indicates a nominal 10 A switching rating with additional suitability for certain lighting loads that can produce higher starting currents, such as fluorescent or inductive lighting circuits. The connected load, lamp driver inrush current, supply voltage and manufacturer documentation must be checked before installation, especially when switching large LED lighting groups.

An intermediate switch is used when one light or lighting group must be controlled from three or more positions. Typical applications include staircases, long corridors, villa hallways, hotel passages, large rooms and multi-entry spaces. The intermediate switch is installed electrically between two two-way switches; additional intermediate switches can be added for more control points.

This model is specifically intended for intermediate switching and should normally be used as part of a multi-location circuit with two-way switches at both ends. For a light controlled from one location, use a one-way switch; for control from two locations, use two compatible two-way switches. Selecting the correct switch type simplifies wiring and helps avoid installation errors.

Installation should be completed by a qualified electrician. After isolating and verifying the circuit is dead, the electrician identifies the two pairs of traveller or strapper conductors, connects them to the terminals according to the wiring diagram and terminal markings, secures the mechanism in a compatible flush or surface box, fits the front plate, and tests switching from every control point. Terminal layout must be confirmed on the actual product rather than assumed from wire colour alone.

An intermediate switch generally requires two pairs of traveller conductors running between the two-way switches at each end of the circuit. The switch changes the relationship between these conductor pairs to open or complete the lighting circuit. Cable size, conductor identification, earthing, containment and circuit protection must follow the approved electrical design and applicable UAE authority requirements.

The switch is relevant to UAE villas, apartments, hotels, offices and commercial fit-outs that require multi-point lighting control and a royal gold decorative finish. Before project approval, contractors should verify the voltage and frequency compatibility, approved product documentation, mounting-box requirements and compliance with the relevant emirate's electrical authority, consultant specifications and project material submittal.

Contractors should confirm the model number BL119-PG, 1-gang intermediate function, 10AX rating, finish, wiring configuration, compatible back box and matching ABB Inora accessories. They should also review the lighting load and LED driver inrush current, cable arrangement, required authority approvals and consultant-approved schedules. Compliance evidence should be checked against current UAE regulations and relevant IEC or British-based wiring requirements specified for the project.

It may be used with suitable LED lighting circuits, but the total wattage alone is not enough to confirm compatibility. LED drivers can generate significant inrush current, particularly when several fittings are switched together. The electrician or engineer should review the number of drivers, their inrush characteristics, the switch manufacturer's load guidance and the circuit design. A contactor or relay may be required for larger lighting groups.

The royal gold finish is well suited to decorative interiors where electrical accessories need to coordinate with gold-toned hardware, lighting fixtures, marble, wood or premium wall finishes. It is commonly relevant to villas, majlis areas, hotel rooms, restaurants and high-end apartments. The switch should be protected from cement, paint, cleaning chemicals and abrasive tools during construction and fit-out work.

Do not assume the switch is weatherproof or suitable for wet locations unless an appropriate IP rating is confirmed in ABB documentation. In bathrooms, outdoor spaces, plant areas or locations exposed to moisture and dust, the installation must meet zoning, enclosure and ingress-protection requirements. A suitably rated weatherproof accessory or enclosure may be necessary under UAE site conditions.

Use a mounting box that matches the ABB Inora mechanism, plate format, fixing centres and required wiring depth. Adequate depth is important because an intermediate switch has multiple conductors that must be arranged without sharp bends or terminal stress. Contractors should confirm dimensional drawings and accessory compatibility before civil works, blockwork chasing or bulk procurement.

Keep the switch and decorative plate in their packaging until dusty or wet work is complete. Avoid installing the finished royal gold plate before plastering, painting, tile cutting or chemical cleaning. If the mechanism must be installed earlier, use suitable temporary protection without trapping moisture. Before handover, inspect the finish, tighten terminals to the specified torque and test operation from every switching position.

First isolate the supply and prove the circuit is dead. Then verify that two-way switches are installed at the ends, the intermediate switch is correctly positioned between them, and both traveller pairs are connected to the correct marked terminals. Check for loose conductors, damaged cables, incorrect conductor identification and defective lamps or drivers. After correction, perform the electrical tests required by the project and confirm operation from all control locations.

A 1-gang intermediate switch controls one lighting circuit from an intermediate location. A 2-gang accessory contains two separately operated switch mechanisms and can control two circuits, provided each mechanism has the required switching function. The term 'gang' refers to the number of controls on the plate, not the number of locations from which a circuit can be operated.
