Micro-miniature surface-mount switches for portable / wearable electronics

C&K Components has released a new series of micro-miniature, SMT top-actuated switches that provide low profile, high actuation force (450gf), and high life cycle (500,000) solutions especially designed to meet the demanding size and performance specifications required of portable electronic devices. With a footprint of just 3.5mm x 2.6mm and an ultra-low profile of 1.4mm, the PTS380 Series switches deliver reliable switching performance within the space constraints imposed by the miniaturization of next-generation wearable electronic devices, portable wireless devices, remote controls, and keyless entry systems. “The PTS380 Series was specifically designed to address the requirements of next-generation miniature portable electronic devices,” said Gustavo Jimenez, product marketing manager, C&K Components. “In addition to the series’ small footprint and low profile, the 450gf operating force option prevents unwanted actuation, which is critical for wearables and keyless entry fobs, and the optional ground pin prevents failures resulting from the discharge of static electricity.” PTS380 Series SMT switches are top-actuated, momentary action devices, with a single-pull single-throw (SPST), normally-open configuration. Rated for 12VDC and 50mA, the switches are available with actuation force options of 160gf and 450gf, and with operating life cycles of 200,000 and 500,000. Travel distance is 0.15mm ±0.1mm, with a typical bounce time of =10ms, and rated operating temperatures for the series span -40C to +85C.
