Tactile Switches(SMD Types)

B3S Sealed Tactile Switch (SMT)

Surface-mounting Tactile Switch for High Contact Reliability

  • Sealed construction conforming to IP67
    (IEC- 60529) provides high contact reliability in locations
    exposed to dust or water. (* Excluding the terminal section.)
  • Surface-mounting terminals for high-density mounting.
  • Ground terminal available to protect against static electricity.
  • Available in embossed taping packages for automatic mounting.
