What Is the 12 Module Switch Board Size?
For Treco's modular-switch range, the visible 12 module switch board plate size is 240 × 182 mm. Converted to inches, this is approximately 9.45 × 7.17 inches.
In centimetres, the same plate measures approximately 24 × 18.2 cm.
| Measurement | Width | Height |
|---|---|---|
| Millimetres | 240 mm | 182 mm |
| Centimetres | 24 cm | 18.2 cm |
| Inches | 9.45 in | 7.17 in |
Important Size Note
240 × 182 mm (9.45 × 7.17 inches) refers to Treco's visible 12 module plate.
It should not automatically be used as the size of the concealed mounting box or wall cut-out. Plate, frame and mounting-box dimensions should be checked as one compatible system before installation.
What Does 12 Module Mean?
A 12 module switch board provides twelve module spaces for compatible electrical controls.
A module is a unit of usable space inside a modular switch system. It does not automatically mean the board can contain exactly twelve separate switches.
Different products can occupy different amounts of module space. A basic switch may require less panel space than a socket, fan controller or another larger device.
This is why the component layout should be selected before the plate and box installation is finalized.
12 Module Switch Board Dimensions Explained
| Dimension | What It Means | Why It Matters |
|---|---|---|
| Visible plate size | The width and height of the finished front plate. | Determines the visible wall area covered by the switchboard. |
| Mounting frame | The structure supporting the switches and front plate. | Must be compatible with the selected plate and devices. |
| Mounting box | The concealed enclosure installed inside the wall. | Must match the selected modular system. |
| Wall cut-out | The wall opening required for the concealed box. | Should be finalized before wall finishing. |
| Internal depth | Usable space behind the switches for terminals and wiring. | Affects wire bends, connections and maintenance access. |
Is 12 Module Plate Size the Same as 12 Module Box Size?
No. The 12 module plate size and 12 module box size are not necessarily the same.
The visible plate sits on the finished wall surface, while the mounting box is installed behind it. The box therefore has its own width, height and depth according to the selected product system.
For this reason, someone searching for a 12 module box size in inches should not use Treco's visible 9.45 × 7.17-inch plate measurement as the concealed box measurement.
There is also no single universal mounting-box size for every 12-module product made by every manufacturer. Always check the matching box for the selected plate and frame.
How Many Switches Fit in a 12 Module Board?
There is no fixed answer because the final number depends on the type and width of each control.
| Component | Effect on Module Space | Planning Check |
|---|---|---|
| Basic modular switch | Usually uses relatively little module space. | Confirm its module width in the selected series. |
| Socket | May occupy more space than a basic switch. | Check size, rating and plug clearance. |
| Fan control | Can reduce the remaining number of available switch positions. | Confirm physical size and electrical rating. |
| Smart touch panel | Uses a predefined panel configuration rather than individual mechanical module pieces. | Check panel configuration, wiring and load compatibility. |
The correct approach is to list the lights, fans, sockets and other functions required at that location, then select compatible components that fit within the twelve-module capacity.
Why 12 Module Switch Board Sizes Can Differ Between Brands
The term 12 module describes modular capacity rather than one universal external width and height.
Manufacturers can use different plate proportions, mounting frames, box designs and product series. Therefore, a 12 module plate from one range should not automatically be paired with a frame or concealed box from another.
Treco lists its 12 module visible plate at 240 × 182 mm. For the matching modular products, see Treco modular switches and plates .
What to Check Before Installing a 12 Module Switch Board
- List all required controls: Count lights, fans, sockets and other functions required at the location.
- Select the actual components: Confirm the module width of every switch, socket and controller.
- Confirm the plate dimensions: Check that the visible plate fits the intended wall area.
- Use the matching box and frame: Do not assume every 12-module frame and box are interchangeable.
- Check internal depth: Allow sufficient space for terminals and wiring.
- Inspect electrical requirements: Confirm load ratings, conductor size, neutral availability, earthing and circuit protection.
- Test before final fitting: Every switch, socket and control should be tested before the finished plate is installed.
12 Module Switch Board Wiring Considerations
A 12 module switch board wiring arrangement depends on the actual devices installed in the panel. There is no single universal wiring diagram for every twelve-module board.
Before installation, the electrician should check:
- The circuits controlled from the location
- Electrical load ratings
- Conductor sizes
- Neutral availability where required
- Earthing
- Circuit protection
- Available enclosure depth
- Terminal and maintenance access
Mains electrical wiring should be completed and tested by a qualified electrician according to the selected devices and circuit design.
Standard 12 Module Board vs Smart Touch Panel
A standard modular board uses individual switches, sockets and other components fitted into a compatible frame.
A smart touch panel uses a predefined electronic control layout. Treco's touch switch range includes 12-module smart touch configurations for suitable installations.
| Feature | Standard Modular Board | Smart Touch Panel |
|---|---|---|
| Control style | Individual mechanical controls | Touch-based electronic controls |
| Layout | Built from compatible individual modules | Predefined panel configuration |
| App integration | Not normally available on basic mechanical switches | Available on compatible smart configurations |
| Planning priority | Module allocation and device ratings | Panel configuration, wiring, loads and compatibility |
What Affects 12 Module Switch Board Price?
There is no meaningful universal 12 module switch board price because different quotations can include very different components.
The total cost may depend on:
- Front-plate material and finish
- Mounting frame and concealed box
- Number and type of switches
- Socket types and ratings
- Fan-control requirements
- Standard or smart controls
- Existing wiring condition
- Installation and testing
When comparing prices, confirm whether the amount is for only the front plate or for a complete configured switchboard.
Common 12 Module Switch Board Planning Mistakes
- Assuming 12 modules always means 12 separate switches
- Using visible plate dimensions as the mounting-box dimensions
- Buying the plate before choosing the controls
- Combining a plate and box from incompatible product systems
- Ignoring internal box depth
- Overcrowding the enclosure with wiring
- Adding smart controls without checking neutral and load requirements
- Finalizing wall work before confirming the required mounting box
12 Module Board Planning Checklist
- Required switches and sockets listed
- Module allocation confirmed
- Visible plate dimensions checked
- Compatible mounting frame selected
- Correct concealed box confirmed
- Internal depth checked
- Electrical loads confirmed
- Neutral and earthing requirements checked
- Smart-control compatibility checked if required
- Installation tested before final handover
Conclusion
For Treco's modular-switch range, the 12 module switch board visible plate measures 240 × 182 mm, approximately 9.45 × 7.17 inches.
The most important point is that this is the front plate measurement. A 12 module mounting box, wall cut-out and internal box depth are separate dimensions and should be checked using the selected compatible system.
The twelve-module designation describes available modular capacity, not a guaranteed number of switches or one universal external board dimension across every manufacturer.
