Retrotouch Switching Guide

Understanding 1-Way, 2-Way & Intermediate Switching

Choosing the correct switch type is essential for ensuring your lighting operates as intended. Retrotouch offers solutions for standard switching, multi-way switching and smart wireless control to suit a wide range of installations.

1-Way Switching

A 1-way switch controls a lighting circuit from one switch location only. This is the most common switching arrangement found in UK homes.

Typical Applications

• Bedrooms
• Bathrooms
• Utility rooms
• Small offices
• Cupboards

How It Works

One switch controls one light or lighting circuit. Pressing the switch turns the light on or off from a single location.

Best For

• Simple lighting installations
• Rooms with one entrance
• Standard on/off control

2-Way Switching

A 2-way switch allows one light to be controlled from two different switch locations.

Typical Applications

• Top and bottom of staircases
• Hallways
• Rooms with two entrances
• Garages with multiple access doors

How It Works

Two switches communicate with each other so either switch can turn the same light on or off independently.

Best For

• Improving convenience
• Eliminating the need to walk back to the original switch
• Residential and commercial applications

Retrotouch offers standard touch switches, rotary dimmers and Smart Wi-Fi switches that support two-way switching.

Intermediate Switching

An intermediate switching circuit is used when one light needs to be controlled from three or more locations.

In a traditional wiring arrangement:

• The switches at each end of the circuit are 2-way switches
• Any switch positioned between them must be an intermediate switch

Typical Applications

• Three-storey staircases
• Long corridors
• Large hallways
• Commercial buildings
• Hotels

Benefits

• Convenient lighting control from multiple locations
• Ideal for larger properties
• Flexible operation without returning to a previous switch

Smart Wi-Fi Switching

Retrotouch Smart Wi-Fi switches provide an alternative to traditional multi-way wiring.

Instead of using conventional strapper wiring between switches, compatible Smart Wi-Fi switches can be linked within the SmartLife app to create:

• Wireless 2-way switching
• Wireless intermediate switching
• Smartphone control
• Voice assistant integration
• Scheduling and automation

This makes them ideal for renovations or smart home upgrades where additional wiring may be difficult.

Choosing the Correct Switch

Note: Retrotouch touch dimmer switches are not conventional 2-way dimmers. For two-way dimming applications, Retrotouch recommends using rotary dimmers.

Installation Notes

• Always isolate the mains supply before beginning installation.
• Installation should only be carried out by a qualified electrician.
• Follow the wiring diagram supplied with your specific Retrotouch switch.
• Ensure all terminal connections are secure before restoring power.
• Smart Wi-Fi switches generally require a minimum 35 mm back box (47 mm recommended for easier installation).

Frequently Asked Questions

Can I use a 1-way switch in a 2-way circuit?

No. Both ends of a traditional two-way circuit require compatible 2-way switches.

Do I need an intermediate switch?

Only if the same light is controlled from three or more locations.

Can Retrotouch Smart Wi-Fi switches replace traditional 2-way wiring?

Yes. Compatible Smart Wi-Fi switches can be paired wirelessly through the Retrotouch app to provide two-way or intermediate operation.

Are Retrotouch touch dimmers suitable for 2-way dimming?

No. Touch dimmers are designed for one-way dimming. Rotary dimmers are the recommended solution for two-way dimming.
