www.us-tech.com Power PB Switches from C&K Components
Newton, MA — C and K Components has developed a power pushbutton switch that incorporates redundant double break contacts. Designated the PWR Series, the RoHS-compliant and IP65-sealed switches reportedly
provide an extended operating life of 100,000 mechanical cycles. According to the company, the
highly reliable switches are vibra- tion-resistant, making them suitable for challenging automotive, industri- al and white goods environments. The PWR Series is suitable for
select white good and appliance main power, industrial panel, automotive, and computer and peripheral power switch applications. The pushbutton switches have a
