C&K Components, a leading international supplier of tact switches, toggle, rocker and pushbutton switches, and smart card interconnect devices, has expanded its family of KSC Series tactile switches. Designated the KSC741 and KSC721 devices, the low profile tactile switches feature a height of only 4.3mm, sealing to IP67 standards and an extended life to one million actuations, making them ideal for high reliability applications.

“The new KSC switches feature an anti-corrosion contact and are offered with gold or silver plating, allowing us to meet different temperature and corrosion resistance classes,” said Eric Grange, product manager for C&K Components. “Due in part to the 4.3mm height, the switches serve as a highly reliable, cost-effective drop-in replacement solution for customers who want or need to change the switch they are currently using but don’t want to redesign the application.

The low profile KSC7 Series switches are ideal for a variety of applications including automotive, consumer electronics such as cellular phones, network infrastructure and IT, and industrial electronics.

The sealed KSC7 Series switches feature a positive tactile feel in a range of six actuation forces. Current rating for the momentary action, SPST, normally open devices ranges from 1mA to 50mA for silver plating and 1mA to 10mA for the gold plating. Contact resistance is less than 100mΩ. Maximum power rating for the silver and gold plating is 1VA and 0.2VA, respectively, with a maximum voltage of 32VDC. Operating temperature ranges from -40°C to +125°C, depending on plating.

The KSC Series switches feature J bend and gullwing terminals, and are available on tape and reel packaging for automated assembly.
