Littelfuse, Inc. announces the C&K Switches KSC DCT Series Tactile Switches. The KSC DCT (Dual Circuit Technology) series are sealed IP67-rated, momentary-action tactile switches for surface-mount technology (SMT).

The KSC DCT is the first tactile switch to offer single pole double throw (SPDT) functionality in a small 6.2 x 6.2 x 5.2 millimeters size. The switches feature a soft actuator that withstands an operating force of 4.75N (+/-1.25N) and has a lifespan of 300K life cycles.

The KSC DCT Tactile Switches offer these key features and benefits:

  • SPDT Functionality: Added reliability due to one input and two outputs in a single tactile switch.
  • Compact Footprint: Fits applications where space is limited.
  • IP67 Sealing: Provides high contact reliability, protecting against dust and water ingress.
  • J-Bend SMT Package: Enables standard assembly mounting using typical pick-and-place machines. (Gullwing-type terminations are also available.)
  • Cost-Efficient: SMT makes it ideal for high-volume applications.

The KSC DCT Series Tactile Switches are ideally suited for:

  • Transportation: Automotive door handles, EV charging station units, two- and three-wheelers.
  • Consumer Electronics: Power tools, lawnmowers, snow blowers, home appliances.
  • Medical Devices: Electrosurgical instruments, portable medical devices.
  • Industrial Applications: Elevators, fire alarm equipment.

The increased safety needs of today’s end users require active failure verification: with the added single pole double throw (SPDT) functionality, the KSC DCT tactile switch allows a system to actively verify failures, like an unwanted door opening.
