B3SN Sealed Tactile Switch (SMT)

Compact Surface Mount Tactile Switch with Sealed Construction

Sealed construction conforming to IP67 (IEC-60529) provides high reliability in locations exposed to dust or water. (* Excluding the terminal section.)
Available with ground terminals for protection against static electricity.
Use of a stainless-steel spring provides a crisp clicking action.
Gold plated version enables stable contact and insulation over long periods of time.
Available in embossed taping packages for automatic mounting.

Note: 1.	All units are in millimeters unless otherwise indicated. Unless otherwise specified, a tolerance of ±0.4 mm applies to all dimensions.
Note: 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.
