Light Switches

A light switch is most commonly used to operate electrical circuits for lighting in homes and industrial sites across New Zealand. A light switch provides an electrical outlet to an appliance or socket that it is either connected to or built in, which allows you to turn a light on or off or in some cases a dimmer to turn to achieve a desired light. Permanent wall light switches allow users to safely break or complete the flow of electricity.

RS supplies a comprehensive range of plate switches and accessories from leading brands like Legrand, Schneider Electric, and RS PRO. Available in various finishes, these switches are essential for matching room décor while ensuring reliable, daily functionality.

Types of Light Switches

Push-Button Light Switches

A push-button light switch operates through a simple press mechanism to open or close the electrical circuit. These are often used in modern interiors across New Zealand for a sleek, minimalist look. A button switch can be momentary, staying active only while pressed, or latching, where the first press turns the light on and the second turns it off.

Timer Light Switches

Timer switches are designed to automatically turn lights off after a set duration, making them excellent for energy efficiency. In New Zealand commercial buildings, these are frequently installed in stairwells, pantries, or bathrooms to ensure power isn't wasted. Many Legrand timer models allow for precise adjustments, ranging from a few minutes to several hours, providing convenient automation for any wall light switch application.

Rocker Light Switches

The rocker is the most common variety of wall light switch found in residential and industrial settings. It features a wide, flat actuator that "rocks" back and forth to toggle the power. Because of their ease of use and reliability, rocker switches are a staple in the New Zealand electrical market. RS offers these in various configurations, including 1-gang to 6-gang plates to control multiple circuits from a single point.

Outdoor Light Switches

Outdoor switches are specifically engineered with high IP (Ingress Protection) ratings to withstand harsh environmental conditions. Whether facing rain in Auckland or dust on a construction site, these switches feature weather-resistant housings and seals. Selecting a robust light switch for external use prevents water ingress and electrical shorts, ensuring the safety of your outdoor lighting and power systems.

Factors to Consider when Choosing Light Switches

Selecting the appropriate light switch involves more than just matching a colour to your wall. To ensure the safety and longevity of your electrical installation in New Zealand, consider the following technical and aesthetic factors:

Circuit Type and Functionality

Before purchasing, identify if you require a one-way, two-way, or intermediate wall light switch. One-way switches control a light from a single location, while two-way and intermediate configurations allow you to operate the same light from two or more different points, such as the top and bottom of a staircase.

Load Compatibility and Dimming

Verify that the button switch or rocker is rated for the specific load it will carry. Some modern light switch models, especially dimmers, have specific minimum and maximum wattage requirements. Using a standard dimmer with non-dimmable LED bulbs can cause flickering or circuit damage, so always check for LED compatibility.

Mounting and Plate Style

The physical design of the wall light switch should suit the mounting box already installed in your wall. Most New Zealand installations use standard rectangular plates, but high-end ranges like those from Legrand offer various slimline or screwless designs. Consider whether you prefer a traditional rocker, a modern push-button, or a touch-sensitive interface.

Gang Requirements

Determine how many individual switches you need on a single plate. A "gang" refers to the number of individual button switch units on the faceplate. RS stocks everything from a 1-gang light switch for simple rooms to 6-gang plates for complex industrial lighting systems or open-plan residential lighting control.

Environmental Durability (IP Ratings)

Assess where the switch will be located to determine the necessary Ingress Protection (IP) rating. Standard indoor switches are not designed to handle moisture. For bathrooms, laundries, or outdoor areas, a specialised light switch with a high IP rating is essential to prevent electrical faults caused by water or dust.

Brand and Build Quality

Choosing reputable brands like Legrand ensures that the internal mechanisms are robust enough for thousands of cycles. High-quality materials prevent the switch from becoming "mushy" over time, maintaining a crisp, audible click and a secure electrical connection.

Industrial Applications of Light Switches

In New Zealand, light switches are used far beyond simple domestic settings. High-traffic and heavy-duty environments require specific wall light switch solutions that can withstand rigorous use and provide reliable control over complex lighting circuits.

Commercial and Office Buildings

Commercial facilities often utilise multi-gang rocker or push-button configurations to manage lighting for large floors or partitioned zones. Brands like Legrand provide modular light switch solutions that integrate seamlessly into office trunking. These installations frequently include timer or occupancy sensors integrated into the button switch plate to reduce energy consumption during non-business hours.

Manufacturing and Factories

In manufacturing, a light switch must be robust and easy to operate, even when the user is wearing gloves. Large-format rocker switches or industrial-grade button switch units are common here, often featuring high impact resistance. These units are designed to survive the mechanical vibrations and dust typical of industrial production lines.

Healthcare and Laboratories

Hygiene is a priority in medical facilities. Specialised wall light switch designs with antimicrobial coatings or touchless sensors help prevent cross-contamination. Certain manufacturers offer ranges specifically designed for clinical environments that are easy to sanitise without damaging the internal electrical mechanisms.

Education and Public Facilities

Schools and public halls require durable light switch options that are tamper-resistant. Heavy-duty metal plates and screwless designs prevent unauthorised removal or damage. In these settings, push-button models are often preferred for their low profile, reducing the risk of accidental breakage in high-traffic corridors.

Warehousing and Logistics

Lighting in warehouses must be managed across vast areas. Standard wall light switch units are often supplemented by remote or automated control systems to manage high-bay lighting efficiently. For manual overrides, ruggedised outdoor-rated switches are frequently used in loading docks and unheated storage areas to resist moisture and temperature fluctuations.

Frequently Asked Questions About Light Switches

What’s the best simple light switch for my home?

You're possibly looking for the most common of switches, which most electricians refer to as a single-pole light switch. This is a switch where when the user flips the lever up, the electrical circuit is complete and the light switches on and when the lever is flipped down the circuit is broken and the light turns off.

Do I need more than one switch?

We supply gang 2 way light switches that hold more than one terminal, allowing you to control more than one light at a time. These types of light switches are usually found at the top and bottom or in a hallway of a flight of stairs. A gang of switches can range between 1-6+.

How do I create ambiance in my room?

Creating the right ambiance involves controlling the intensity of your lighting to suit different moods or tasks. A dimmer switch is the most effective wall light switch for this purpose, allowing you to transition from bright, functional light to a soft, warm glow.

For a modern aesthetic in New Zealand homes, you might consider a push-button dimmer or a touch-sensitive button switch. These offer precise control and often include a memory function that returns to your last used brightness level. Brands like Legrand offer stylish, integrated dimming solutions that replace a standard light switch, providing an easy way to upgrade the atmosphere of any living space or commercial showroom.

What does “number of gangs” (1‑gang, 2‑gang, 3‑gang, etc.) mean?

In the electrical industry, the term “gang” describes the number of individual switches located on a single faceplate. A 1-gang light switch features one button switch, whereas a 3-gang plate houses three separate switches to control three different lighting circuits from one central wall light switch location.

Can I use a dimmer switch with LED lights or other bulb types?

You can use a dimmer, but compatibility depends on the technology of both the bulb and the switch. Standard dimmers designed for incandescent bulbs often fail to work with LEDs, leading to flickering or poor performance. To ensure a smooth dimming range, you can pair a dimmable LED bulb with a trailing-edge light switch specifically rated for LED loads.

Do I need a special (waterproof / outdoor‑rated) switch for bathrooms, garages, or outdoor areas?

Yes, safety regulations in New Zealand require specific Ingress Protection (IP) ratings for switches in "wet zones." While a standard indoor push-button might suffice for a dry hallway, bathrooms and laundries often require switches with internal seals. For garages or exterior walls, you must use a dedicated outdoor light switch housed in a weatherproof enclosure (typically IP66) to protect against moisture and dust ingress.
