Dimensions (Unit: mm)
Note: The numbers used for terminals in the following graphics are indicated in the “Bottom View” diagram below. In this
diagram, the Switch is rotated so that the terminals are on the right and left-hand sides, and the OMRON logo appears
the right way up.
6 6 mm Models
Note: Unless otherwise specified, a tolerance of ±0.4 mm applies to all dimensions. No terminal numbers are indicated on the Switches.
Key Tops
B32-series Key Tops are available for projected plungers. Refer to the Datasheet of B32 for details.
Precautions
Be sure to read the safety precautions common to all Tactile Switches for correct use.
