Newton, Mass. — C&K Components introduced a new series of high reliability, ergonomic keyboard switches for applications that require long operating lifetimes, including gaming, industrial, professional, and workstation keyboards. The KBD Series switches, rated for an extended operating life of 50,000,000 cycles, are available with two haptic responses and operating forces.
The switches are top-actuated, single pole/single throw (SPST) devices with a pre-travel distance of 1.5 – 2 mm, and total travel distance of 4 mm. They feature a range of operating forces color-coded to the knob and one of two haptic responses: linear actuation for 60 ± 20 gf black and 45 ±20 gf red knobs, and click-pressure-point actuation for 60 ±20 gf blue and 55 ±20 gf brown knobs.
The switches are supplied with gold contacts rated for 10 mA at 12 VDC and lead-free, RoHS compliant, tin-plated terminals. The operating temperature range is -10°C to +70°C.
