Tactile switch pushes miniaturisation envelope for wearables

Tactile switch pushes miniaturisation envelope for wearables

The company describes it as ‘surface-mount’, but ‘edge-mount might’ be a better term as it is designed to fit onto the edge of a PCB, protruding  0.95mm above the PCB surface height.

PTS847 is the name of the series, and according to C&K it can handle the drop-impacts common to consumer devices – it is available with an optional rugged bracket which has an L-shape termination (see photo) that provides additional soldering strength in the operating direction.

There are two force options: 160g or 350g.

Operation is over 0 – 15V, 0 – 20mA, -40 to 85˚C and 200,000 actuation cycles.

Resistances are 100mΩ contact and 100MΩ minimum for insulation. Dielectric voltage is 250Vac.

“The compact side-actuated PTS847 Series increases reliability, and eliminates integration challenges for designers of wearable and portable IoT devices,” said C&K product manager Daisy Liu. “We are proud to continue expanding the PTS switch family to enable customers to reduce the size of their end products without compromising performance and reliability.”
