Tactile Switch (Sealed SMD Type) – B3S
Tactile Switches
Surface-mounting Tactile Switch for
High-density Packaging
■
ROHS compliant.
■
Dust-sealed construction provides high
reliability in locations exposed to dust.
■
SMD Tactile Switch ideal for high-density
mounting.
■
Sealed construction conforming to IP64
(IEC-529). Can be washed after soldering.
■
Ground terminal available to protect against
static electricity.

Nomenclature
Note 1. All units are in millimetres unless otherwise indicated. Unless otherwise specified, a tolerance of ±0.4 mm applies to all
dimensions.
2. No terminal numbers are indicated on the Switches. 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.
