C&K Mid-Travel Tact Switch Offers Customization and Soft Sound


November 25, 2020

C&K has added a 12mm mid-travel tact switch with soft sound and positive haptic feeling solution to its comprehensive tactile switch product offering. Featuring an industry standard 12 mm x 12 mm footprint, the high reliability SFS Series is rated to sealed IP40 dust proof and supports up to 300K cycles. Simplifying integration into a broad range of customer designs and applications, the SFS Series provides three customizable actuation forces including 360gf, 680gf and 970gf.

Offering soft sound and positive tactile feedback, the SFS Series is commonly used in vehicle interior, industrial automation, and medical equipment control applications.

The SFS Series tact switch has gold plating contacts that provide reliable switching with low contact resistance, which can handle the low currents. Available with SMT Terminals, the SFS Series reduces process time to deliver production costs saving for OEM/EMS manufacturers.

“Designed to meet customer requests, the mid travel SFS Series tact switch has a soft actuator and seal contact system that offers rugged, dust-proof performance for long-term operation,” said Daisy Liu, Global Product Manager at C&K.
