KSC9 Series Sealed Tactile Switch

July 5, 2012

The surface mountable KSC9 Series switch delivers a specific actuator with a groove for button clipping and compatibility. The IP67-sealed KSC9 Series tactile switch features a unique design that provides simple integration by way of adjustable height with buttons, full SMD pick-and-place capability, and overload resistance.


The rugged KSC9 Series has an extended life expectancy of 300,000 actuations, making it ideal for harsh environment applications including industrial electronics, network equipment, and telecommunications devices. 


The SPST momentary switch improves upon other available designs by sustaining better guidance and tactile effects with top actuation capacity. The ideal operating temperature range for the KSC9 Series is -40 to 185°F (-40 to 85°C) but can work in specific applications under a peak of up to 257°F (125°C). The operating force of the switch is 2N, 3N, and 4N.
