2-Gang, 4-Gang or 6-Gang Smart Switch? Plan the Buttons and Circuits

Illustrative home setting with a non-illuminated StellarTrack switch. Generated image; not a photograph of a completed installation.

Start with the lights you want to control independently, then add any scene shortcuts you will actually use. The number of buttons on a smart switch does not always equal the number of wired circuits it can switch. Confirm both before ordering a 2-, 4- or 6-gang smart switch.

This guide focuses on planning the controls at one wall position. If you are still choosing a system, begin with our complete guide to smart light switches in Australia.

What are you counting: buttons, circuits or scenes?

Product names may use “gang” to describe a panel layout. For a smart switch, check the specifications behind that label. Three different numbers matter:

• Physical buttons: the controls you can press on the front of the panel.
• Switched circuits: the separate wired lighting loads controlled by the switch’s relay outputs. Several light fittings may share one circuit.
• Scene controls: buttons configured to trigger supported actions through your smart-home system. They can provide extra shortcuts without adding another wired relay output.

For example, wanting separate control of ceiling lights and pendants is a circuit requirement. Wanting an “Evening” shortcut that sets several compatible devices together is a scene requirement. Write these down separately so that a larger panel does not hide a missing circuit.

A concrete example from the StellarTrack range

The current listing for the non-illuminated StellarTrack Matter Smart Switch (Thread) specifies the following layout choices. These figures describe that product, and should be confirmed for the exact configuration you order.

• 2-button layout: the listing specifies two switched circuits. Consider it when two independent wired lighting groups cover the job and you do not need a larger set of wall shortcuts.
• 4-button layout: the listing specifies up to three switched circuits, with remaining buttons available for scene use. It can be worth considering when the room needs up to three wired groups plus an additional supported scene control.
• 6-button layout: the listing still specifies up to three switched circuits. The extra buttons provide room for more supported scene controls; they do not turn this model into a six-circuit switch.

The StellarTrack manual describes button and relay decoupling, including relay and scene modes. It is a family-level manual, so use the selected product’s specifications and order confirmation for the precise button-to-circuit mapping.

Keep the two StellarTrack products separate. The Light & Sensor model has its own listing and configuration. Its built-in sensor adjusts the button backlight; it does not automatically switch or dim the room lights in response to occupancy.

Write a room-control brief before choosing a panel

A short list is more useful than choosing the largest panel first. For each wall position, note:

• Every lighting group you want to switch separately, such as ceiling lights, pendants or wall lights.
• Any scene shortcuts you would genuinely use, such as “Evening” or “All lights off”.
• Whether the same lights also need control from a second wall position.
• Which controls should remain obvious to guests or family members who will not use an app.
• Your chosen smart-home platform and the exact controller or hub you already own.

Illustrative planning example: a living and dining area needs separate ceiling lights and pendants, plus an “Evening” scene. That is two desired lighting groups and one scene shortcut. Ask the supplier and electrician which selected configuration can provide those functions in your platform. The example is a planning brief, not a wiring plan or a claim that every platform exposes every button in the same way.

If your brief calls for four independently switched wired groups at the same position, the three-circuit limit listed for the non-illuminated StellarTrack 4- and 6-button models needs attention. Adding more scene buttons alone will not meet that requirement. Ask your electrician to design a suitable arrangement before buying.

Check scene support in your chosen platform

Confirm what a scene button can trigger in the app you intend to use. Ask the supplier to distinguish relay control, button events and any decoupled mode supported by the selected model and platform. A claim that a device works with Matter does not, by itself, explain the behaviour of every button.

For a typical Matter over Thread home setup, check for a compatible Matter controller and a Thread border router. Some devices provide both functions. Check the exact model rather than assuming every smart speaker or hub has Thread support.

For Google Home, Google’s Matter setup requirements distinguish hubs that support Thread from hubs that only support Matter over Wi-Fi. For Apple Home, check Apple’s current home-hub and Thread accessory guidance against your exact HomePod or Apple TV model.

Also ask what happens if the internet or a required hub is unavailable. A directly switched load and a platform scene have different dependencies. During commissioning, have the installer demonstrate the normal wall-button behaviour and the agreed fallback behaviour.

Have an electrician confirm the physical fit

Before ordering, ask a licensed electrician to confirm the neutral wire, wall-box dimensions, load types and ratings, and any two-location switching arrangement. The non-illuminated StellarTrack listing states that a neutral wire is required at the switch.

Do not remove the wall plate or identify conductors by colour yourself. Energy Safe Victoria’s household guidance identifies changing light switches as electrical work for a licensed electrician. Use the product’s technical documents for the installation assessment.

Dimming is a separate check. More buttons do not establish that a switch can dim a connected light. Confirm the exact dimming hardware, lamps and intended controls before treating dimming as part of your plan.

Your pre-order checklist

• Selected product: exact model and option, including button count and panel finish.
• Wired loads: the number of independently switched groups, checked by the electrician.
• Button jobs: which buttons switch relays and which, if any, trigger scenes.
• Platform: confirmed scene support, compatible controller and Thread border router where required.
• Installation: neutral, physical fit, load compatibility and any second control position.
• Order details: selected-option price, current availability and any additional equipment or installation work.

Compare the smart switch range once that brief is clear, then send Arklyfe the chosen product and the functions you need confirmed. A clear control plan helps you choose the smallest layout that does the job without paying for buttons you will not use.

Quick answers

Does a 6-gang smart switch control six lighting circuits?

Not necessarily. Check the relay specification separately from the front-panel button count. The current non-illuminated StellarTrack listing specifies up to three switched circuits for its 6-button layout, with additional buttons for scene use.

Is a 4-button layout better than a 2-button layout?

It depends on the control plan. Two independent wired lighting groups may be enough for one room. Another may need a third wired group or a supported scene shortcut. Choose against those functions and the selected model’s specifications.

Is “2-gang” the same as “2-way” switching?

They describe different requirements. A panel’s gang or button count concerns its layout; two-way switching concerns controlling the same light from two locations. Have the electrician confirm the supported arrangement for the exact model.

Can I choose a 6-button model just to get dimming?

No. Button count does not establish dimming capability. Check the selected switch, any separate dimming equipment and the lamps as a complete setup.
