Sealed Tactile Switches suit high-reliability applications.

Press Release Summary:

Featuring low-profile (4.3 mm) design and positive tactile feel in range of 6 actuation forces, KSC741 and KSC721 are sealed to IP67 standards and offer extended life of one-million actuations. Anti-corrosion contact and gold or silver plating address different temperature and corrosion resistance classes. Current rating for momentary action, SPST, NO devices ranges from 1-50 mA (silver plating) and 1-10 mA (gold plating), and respective max power rating is 1 and 0.2 VA.

C&K Expands Family of Sealed Tactile Switches with High Reliability, Low Profile Devices

Robust, cost effective switches serve as drop-in replacement for existing components...

NEWTON, MA (February 11, 2009) - 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 100mW. 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.

Typical pricing for the KSC7 Series switches ranges from $0.19 to $0.15 in minimum order quantities of 10,000 pieces.
