C&K Switches KSC Sealed Tact Switches for SMT
C&K Switches KSC Series Sealed Tact Switches for SMT are ultra-long life switches designed to withstand intensive use and last up to 5 million cycles. The silicon actuators facilitate switch integration and provide possible pre-travel and post-travel depending on force and actuator hardness. The switches best match applications such as elevator and joystick buttons that require resistant switches. The KSC Series exist in both J bend and Gullwing versions to better fit the chosen soldering process.
