C&K Introduces New Five-Million-Cycle Ultra Long Life SMT Tact Switches for Demanding Applications

Designed to withstand intensive use in elevator, joystick, automotive, industrial, medical & aircraft applications, the new IP67-rated KSC Series ultra long life switches are completely customizable with regard to haptics, resistance & durability

C&K Components, a leading global manufacturer of electromechanical switches, smart card interconnect devices, and high reliability connectors, has expanded its KSC Series sealed SMT tact switches with the addition of four ultra long life switches that deliver up to 5 million cycles. Featuring momentary action functionality, single-pole, single-throw (SPST) contact arrangement, the IP67-rated KSC Series ultra long life switches are designed to withstand intensive use in various industrial environments, and are available with a wide variety of actuators designed to satisfy specific application requirements with regard to dimensions, haptics, tactile resistance, and durability. As such, the new ultra long life KSC Series switches are ideal for a range of demanding applications, including: elevator, joystick, automotive, industrial, medical, and aircraft applications.

The customizable haptic and acoustic response of KSC Series switches makes them ideal for interior automotive controls, and their IP67 sealing and durability make them well suited for exterior automotive applications, including door handles and trunk openers. Their durability, rugged sealing, and resistance against steam and corrosive agents make them an ideal solution for harsh industrial applications, such as fire alarm detectors and anti-tampering applications. These features, in combination with the series’ excellent tactile feedback, also enable KSC Series switches to be used in surgery tools and other medical applications, cockpit control units, high-end stereo equipment, and network infrastructure and IT equipment.

Shared features of all KSC Series ultra long life SMT tact switches include: dielectric strength ≥250Vrms, contact resistance <0.1Ω, insulation resistance >10MΩ, and bounce time <1ms. KSC Series switches are rated for 32VDC maximum voltage, 50mA maximum current for silver contacts (-40°C and 85°C), and 10mA maximum current for gold contacts (-40°C and 125°C). Additionally, all four ultra long life switches — the KSC2, KSC4, KSC7, and KSC10 Series — are available with either J-bend and gullwing terminals, and are packaged on continuous tape and reel in quantities spanning 1,000 to 2,000 pieces.
