B3WN Sealed Tactile Switch
Through-hole-mounting Switches
with a Double-sealed Structure
for High Resistance to Water and Dust.
Available on Radial Tape
Sealed construction conforming to IP67 (IEC-
60529) provides high reliability in dusty or humid
environments. (* Excluding the terminal section)
As compact as 8 mm × 8 mm.
• Allows the use of radial-taping part insertion
machines.
