Taking miniaturisation to a new level, C&K's PTS830 series of SMT
top-actuated switches, which offer a high actuation force of up to 450gf,
are now available from Astute Electronics. The switches provide reliable
switching for wearable electronics, portable wireless devices, remote
controls and keyless entry systems.
Gary Evans, divisional manager, e-mech, Astute Electronics, said: “These
switches were designed to address the requirements of next-generation
miniature portable electronic devices. The high operating force prevents
unwanted actuation, which can be critical for wearables and keyless entry
The long 500,000 life cycle suits the demanding performance specifications
of portable electronic devices. And with a footprint of only 3.5mm by 2.6mm
and a height of just 1.4mm, the PTS830 switches deliver reliable switching
performance in the small spaces found in next-generation wearable electronic
devices. Devices 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 160 and
450gf, and with operating life cycles of 200,000 or 500,000. Travel distance
is 0.15mm ±0.1mm with a typical bounce time down to 10ms. Rated operating
temperature is -40C to +85C.
Contact resistance is up to 100mohm and insulation resistance 100Mohm or
above. They are suitable for reflow soldering in accordance with IEC61760-1,
says the company.
