Mechanical Key Switch (SMD)
Surface-mounted Device (SMD) Design
Meets High-density Mounting
Requirements
The whole switch body can be washed after
soldering due to its sealing property.
Sealed construction provides high reliability in
dusty environments.
Available with ground terminal for protection
against static electricity.
Positive tactile feedback.
Fully sealed.
