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.

Note:

Unless otherwise specified, a tolerance of

±0.4 mm applies to all dimensions. No terminal numbers are indicated on the Switches.

B32-series Special Key Tops are available for projected plunger models. Refer to the Datasheet of B32 for details.

Be sure to read the safety precautions common to all Tactile Switches for correct use.
