KSx switches

Switch and interconnect devices provider C&K Components has released a series of automotive-grade tactile switches. The KSx series are based on C&K's KSC and KSA Mk2 tactile switches, and are suited for harsh environments, being highly resistant to corrosion and chemical aggressions.

"The KSx series tact switches provide superior resistance to corrosive gas, salt spray and humidity, making them ideal for outdoor automotive and industrial applications," said Eric Grange, product manager for C&K. "Coupled with features also available with the KSC and KSA Mk2 series switches including specific tactile effects, sound control, extended life cycles to 1 million (10 lakh) operations and IP67 sealing, the KSx series switches meet any harsh environment application needs."

Typical applications for the KSx series automotive-grade switches include door handles and opening panels, as well as locking latch and detection functions. The KSx switches are also suitable for industrial applications where humidity, temperature variation and polluted atmosphere are concerns, including lift keyboards and process control systems, as well as outdoor home appliances.

In addition, the tactile switch series is compliant with the ISO TS16750-4, climatic class D (salt spray, ice water, rapid temperature cycling, 4 mix gas) and temperature class K (-40°C to +125°C) automotive standards. Voltage range for the tactile switches is 20mV to 32Vdc and current ranges from 1mA to 50mA. Contact resistance is less than 100mΩ, with a bounce time of less than 1ms. Power ratings are 1VA for the silver plating and 0.2VA for the gold plating. The switches are available in tape and reel packaging.

Typical pricing for the KSx Series tact switches ranges from Rs.21.88 to Rs.17.50 ($0.45 to $0.36) each in quantities ranging from 10K pieces to 500K pieces. Lead time, if stock is not available, is from six to eight weeks.
