Based on the datasheet details, there are two sets of dimension information that may be relevant:
PCB Footprint Dimensions:
The recommended footprint is given as SW4-SMD-5.2X5.2X1.5MM. This indicates that for PCB layout, the switch’s physical contact area is approximately:
Length: 5.2 mm
Width: 5.2 mm
Height: 1.5 mm
Packaging/Mechanical Dimensions:
The datasheet also lists a range of overall package dimensions. For example, under the “Dimensions (mm)” section you’ll see available options for:
Width (W): Options such as 10 mm, 11.5 mm, or 12 mm
Depth (D): Values like 11.9 mm or 7 mm
Height (H): Multiple options are listed (e.g., 7.1 mm, 11.3 mm, 4.3 mm, etc.)
Additionally, note that the PCB mounting hole dimensions are stated as 2.6 mm × 4.8 mm (measured from the switch mounting face).
If you need to design with this part, please verify which set of dimensions is most relevant for your application (PCB footprint versus overall product packaging).
