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
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.
