Cover Frames

Different types of cover frames

Cover frames are available in various types, each designed for specific applications and aesthetic preferences. The most common differentiation is the number of 'modules' or 'elements' the frame can accommodate, ranging from single to multiple.

Single cover frames for one function

This type is suitable for a single switch, socket, or dimmer. It creates a clean and minimalist finish when only one function is needed in a location. Single cover frames are often used in spaces where aesthetic simplicity is key, such as for individual light points or sockets. Standard dimensions for a single cover frame are around 80 x 80 mm.

Multiple cover frames for multiple functions

Multiple cover frames provide space for two, three, four, or even five modules side by side. They are ideal for situations where multiple functions are combined in one place, such as a combination of switches and a socket, or several dimmers. This contributes to a tidy appearance and reduces the number of visible edges on the wall. Multiple cover frames can be mounted both horizontally and vertically, depending on the required orientation.

The general dimensions of multiple cover frames vary based on the number of modules. A typical double cover frame is approximately 80 x 151 mm, while a triple frame measures around 80 x 222 mm. These standard dimensions ensure compatibility with most back boxes, whether mounted horizontally or vertically.

Technical specifications that define a cover frame

When selecting a cover frame, various technical specifications are important to ensure functionality, safety, and a proper installation. These properties influence the product's applicability and durability.

Protection rating (IP rating) against water and dust

The IP (Ingress Protection) rating indicates the degree of protection of the cover frame against the ingress of solid objects (dust) and liquids (water). For wiring accessories in dry indoor areas, IP20 or IP21 is usually sufficient. For damp areas such as bathrooms or kitchens, cover frames with a higher IP rating, often IP44 in combination with a sealing set, are necessary to ensure splash-proof protection. Always check the required IP class for the specific installation location.

Material quality and its influence on durability

Cover frames are produced from various plastics, such as thermoplastic or duroplast. Thermoplastic cover frames are more flexible and generally more affordable, while duroplast is known for its hardness, scratch resistance, and heat resistance, resulting in a more robust and durable product. Both materials are often halogen-free, which contributes to fire safety by producing fewer toxic fumes in case of a fire.

Installation and the depth of cover frames

The depth of a cover frame (usually between 9 and 12 mm) is an important measurement to consider, especially with shallow back boxes. The cover frame is placed over the base elements and seals the assembly, making the depth of the combined components crucial for a flush wall installation. It is often attached with a clamp fitting on the modules themselves, which ensures an invisible and sleek installation.

Flexibility in installation: horizontal and vertical

Most cover frames are designed for both horizontal and vertical installation. This offers flexibility during installation, depending on the orientation of the back box or the desired aesthetic. This feature is particularly relevant for multiple cover frames, where the orientation can affect the functionality of the connected elements.

Materials and colours that define the appearance

In addition to functionality, materials and colours play an important role in the aesthetics of a cover frame. The material affects the durability, feel, and final look in a room. Plastic is the most common choice, available in various finishes and colours, including:

• Plastic: This is the standard due to its durability, ease of cleaning, and wide availability in colours. Popular choices are polar white (matt) and pure white (glossy), but cream, anthracite, and black versions are also widely available.
• Glass: Glass cover frames offer a modern and luxurious look, often in black or white. They are scratch-resistant and reflect light, which gives a sense of depth.
• Metal: Versions in stainless steel, aluminium, or bronze offer an industrial or classic look and are very robust.
• Natural materials: For exclusive projects, there are cover frames made of wood, slate, or concrete, which give a unique character to the space.

The colour and material should be matched to the interior and the desired atmosphere. A white cover frame provides a neutral and timeless look, while black or anthracite can offer a modern contrast. For a minimalist look, a cover frame that matches the wall colour is often chosen.

Practical installation of a cover frame

Installing a cover frame is relatively simple but requires precision for a clean result. The cover frame is installed after the base elements (switch, socket, dimmer) are correctly mounted in the back box and electrically connected.

1. Ensure safety: Always turn off the power at the consumer unit (fuse box) before starting the installation or removal of wiring accessories. This is crucial to prevent electric shocks.
2. Position the base element: Securely mount the switch or socket in the back box using the designated screws or claws. Ensure it is correctly aligned with the wall.
3. Attach the cover frame: The cover frame clicks or screws onto the base element or a mounting frame. In most modern series, the cover frame simply clicks onto the module(s), making screws invisible.
4. Install the central plate/rocker: As the final step, the central plate (for a socket) or the rocker (for a switch) is clicked or screwed into the cover frame.
5. Check the installation: Check that everything is secure and there are no gaps. Then, turn the power back on.
