Tactile Switch (Doubled-sealed Type) – B3WN
Tactile Switches
Double-sealed Construction
Ensures Watertight and Dust-tight
Performance
■
ROHS compliant.
■
Sealed construction conforming to IP67
(IEC-529) provides high reliability in dusty
or humid environments.
■
As compact as 8 mm x 8 mm.
■
Allows the use of radial-taping part insertion
machines.
