B3SN Sealed Tactile Switch (SMT)
Sealed Surface-mounting Switches Sealed Structure for High Reliability. Available on Embossed Tape
- 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.
- A small package containing 100 embossed taping reels is available,in addition to the standard pack- age.
RoHS Compliant
