B3SE Ultra-thin Sealed Surface-mounting Tactile Switch

Tactile Switches SMD Types: B3SE

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 section.)
  • 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.
