Product Information
Full details
This Knightsbridge Intermediate Switch (CU1200 A) is designed for homeowners and electricians needing to control a single light fixture from three or more locations. Its key benefit is enabling complex multi-way switching circuits, ensuring all switches function correctly regardless of their position. A potential caveat is its specific use case for intermediate switching only, requiring other types of switches for a complete circuit.

FAQs
What is an intermediate switch used for?
An intermediate switch is used in a lighting circuit where the light needs to be controlled from three or more different locations. It works in conjunction with two-way switches.
Can I use this as a standard light switch?
No, this is specifically an intermediate switch. It cannot function correctly as a standalone one-way or two-way switch. It must be part of a circuit with at least two two-way switches.
How many intermediate switches can I use in a circuit?
You can use multiple intermediate switches in a single circuit, as long as they are correctly wired between the two end two-way switches. For example, a 4-way switching circuit uses two 2-way switches and two intermediate switches.
What is the difference between a two-way and an intermediate switch?
A two-way switch has two terminals and is used at the ends of a switching circuit (controlling from two locations). An intermediate switch has four terminals and is used in the middle of a circuit (controlling from three or more locations).
Do I need a special back box for this switch?
This switch typically fits into a standard UK-style single or double back box, depending on your existing wiring configuration. Ensure the back box is suitable for the depth of the switch.
What is the current rating of this switch?
The product description does not explicitly state the current rating, but Knightsbridge switches are typically rated for standard lighting circuits, often 6A or 10A. For precise specifications, refer to the product packaging or manufacturer's detailed datasheet.
Troubleshooting
Light does not turn on/off correctly from all switches.
Verify that all switches in the circuit are correctly wired as either two-way or intermediate. Ensure the intermediate switch is placed correctly in the sequence of three or more switches. Check all connections for looseness.
Switch feels loose or unstable.
Check that the mounting screws are tightened securely to the back box. Ensure the back box itself is firmly fixed to the wall.
Plastic casing or plate appears damaged.
If the damage occurred during installation, carefully re-read installation instructions and ensure no excessive force was applied. If damaged during normal use, the unit may need replacement.
Pros and Cons
Pros
- Allows for control of lights from three or more locations.
- Provides a clean and modern aesthetic with its contoured design.
- Screw cap covers offer a discreet and finished look.
- Reliable performance expected from the Knightsbridge brand.
- Versatile white color fits various room decors.
Cons
- Only suitable for intermediate switching applications; cannot be used as a standard two-way or one-way switch.
- Requires specific wiring configurations which may be complex for DIY installations.
- A single unit does not control the light on its own; it's part of a multi-switch system.
- No smart home integration or advanced features.
Setup, Compatibility & Care
Setup: This switch requires wiring as part of a multi-way switching circuit. It is crucial to follow the correct wiring diagram for intermediate switches, typically involving two two-way switches and one or more intermediate switches. Ensure power is isolated before attempting installation. Consult a qualified electrician if you are unsure about the wiring.
Compatibility: This switch is designed for use with standard household electrical systems. It is intended for controlling lighting circuits and should be used with compatible wiring accessories. It is not designed for use with low-voltage lighting systems without appropriate transformers or relays.
Care: To clean the switch, first ensure the power supply is turned off at the consumer unit. Use a soft, dry or slightly damp cloth to wipe the surface. Avoid using abrasive cleaners or solvents, as these can damage the finish.
