C&K's KSC201, KSC401, KSC701, and KSC1001 switches are designed to withstand intensive use, such as in network infrastructure and industrial electronics. They are ultra-long-life switches that can last up to five million cycles. The silicon actuators facilitate the switch integration for it, which is providing possible pre-travel and post-travel depending on force and actuator hardness. These switches best match applications such as elevator and joystick buttons that require resistant switches. They exist in both J bend and Gullwing versions to better fit the chosen soldering process.
