C&K has introduced the KSH series of surface-mount, top-actuated tactile switches which offers a range of actuation forces and a long operating lifecycle.

The two-terminal and four-terminal styles are both housed in a 6.3mm x 6.3mm x 5.0mm package.

The KSH series tactile switches are single-pole, single-throw, devices with a soft-touch feel. They are supplied with operating- force ratings of 1.6N, 2.0N, 2.5N, 3.0N and 3.5N, and a travel distance of 1.3mm.

Their contacts are rated for currents of 10μA minimum and 50mA maximum, and voltages of 2V DC minimum and 12V DC maximum.

Operating life is 200,000 cycles for devices with an operating force of up to 3.0N.

The KSH series switches offer an economical alternative to rubber keypads, since they can be mounted using standard pick-and-place assembly equipment. The switch incorporates a high-grade silicone which provides consistent tactile ratios over the operating lifecycle, and the design of the moving contact gives it a stable contact resistance with no audible rattling.

FEATURES

  • Operating-temperature range: -40°C to 90°C
  • <100mΩ contact resistance
  • 250V AC dielectric strength
  • >100MΩ insulation resistance

APPLICATIONS

  • Automotive interiors
  • Audio-visual equipment
  • Electronic musical instruments
