Sealed Tactile Switch (SMT)

Surface-mounting Tactile Switch for

High Contact Reliability

• Sealed construction conforming to IP67 (IEC-

60529) provides high contact reliability in loca-

tions exposed to dust or water. (

* Excluding the

terminal section.)

• Surface-mounting

terminals

for

high-density

mounting.

• Ground terminal available to protect against static

electricity.

• Available in embossed taping packages for auto-

matic mounting.
