National Light Sources | 4 Gang Switch 10A 250V | Classic Style White
The NLS 30620 is a four-gang light switch rated for 250V AC. It controls up to four separate circuits from a single plate and suits residential and commercial lighting control. The 30620 is part of the Classic series, the most widely used switch range in Australia.
The 30620 matches standard Classic-style fittings, making it ideal for renovations needing consistency across a property. The mechanism rotates 90 degrees during installation, allowing vertical or horizontal mounting. This flexibility helps on new builds or additions where layout and aesthetics require non-standard orientation. Each unit arrives complete with a white clip-on cover and two installation screws for standard wall boxes.
Electricians favour the NLS Classic range because it has been the market standard for decades. Stock rotation is straightforward. Replacement skins match across retrofit jobs. The interchangeable mechanism and backing plate means all switches from 1-gang to 6-gang use the same internal parts. This consistency cuts inventory complexity and guarantees exact matches when upgrading homes or refitting rooms. The 30620 is an easy upsell when customers want all four circuits on one plate instead of multiple single or dual switches.
Features
- 4 Gang switch mechanism — controls up to four separate lighting circuits from a single plate, reducing clutter and simplifying control in multi-circuit rooms.
- Classic series design — matches the most widely used switch range in Australia, ensuring compatibility with existing and replacement fittings across residential and commercial properties.
- 250V AC rated — standard 10A capacity for general-purpose lighting and switching on 10A MCB or RCD protected circuits.
- Vertical or horizontal installation — the internal mechanism rotates 90 degrees during fit-off, allowing natural or sideways orientation to suit the wall layout and aesthetic preferences.
- Clip-on white cover plate — supplied complete with backing frame and cover, no additional parts needed; the cover snaps off easily for access during installation or troubleshooting.
- Flush mounting on standard wall boxes — installs into 16mm or 20mm deep Australian wall boxes with no adjustment; two supplied screws secure the backing plate firmly.
- Interchangeable mechanism and backing plate — all NLS Classic switches from 1-gang to 6-gang share the same internal mechanism and backing, so electricians can stock one base assembly and swap covers for different gang counts and finishes.
- One-year warranty — covered under NLS one-year domestic and commercial warranty from invoice date, covering manufacturing defects; warranty claims handled via Sparky Direct.
- Interior use only — not rated for external walls, damp areas, or weatherproof installations; use only on dry indoor lighting and general-purpose circuits.
- No tools required to fit — screwdriver fits the mechanism terminals and wall-box fasteners; no specialist tools or training needed beyond standard domestic electrical installation.
Where to use
- Residential lighting circuits — the NLS 30620 is the standard choice for controlling multiple light zones (lounge and kitchen, entry and hallway, bedroom and ensuite) from a single wall plate.
- Home renovations and retrofits — the Classic range matches nearly all existing white switch fittings in Australian homes, making the 30620 an easy upgrade when replacing aged or failed switches.
- New builds and extensions — flex the orientation (vertical or horizontal) to suit the wall layout, and use the same backing plate and mechanism for every switch gang on the job.
- Rental properties and holiday homes — grouped switches reduce guest confusion and accidental overcurrent on multi-appliance rooms; four circuits on one plate is more obvious than scattered single switches.
- Commercial small spaces — office back rooms, small retail storage, staff rooms, and reception areas often benefit from grouped switching for convenience and equipment control.
- Upgrading from single and double switches — when existing 1-gang or 2-gang switches prove insufficient, replace with the 30620 on the same backing plate and wall box.
The NLS 30620 is not suitable for external walls, damp areas, bathrooms, kitchens with splash zones, laundries, or outdoor and weatherproof installations. It is designed for interior dry circuits only. For wet areas, use a weatherproof switch rated to IP66 or higher.
