B3SE Ultra-thin Sealed Surface-mounting Tactile Switch

PCB surface-mounting 6-mm square type that achieves high durability with an ultra-thin, sealed structure.

  • A height of 2 mm contributes to the development of thinner and
    smaller devices.
  • Sealed construction conforming to IP67 (IEC 60529) provides high
    contact reliability in dusty environments. (* Excluding the terminal
  • Crisp click feeling and high durability of 1million operations.
  • Surface-mounting pin type is suitable for high-density mounting.
  • A small package containing 100 embossed taping reels is available,in addition to the standard package containing 2000 reels.
