June 26, 2019 Alix Paultre

C&K introduced the PTS636 and PTS526 sub-miniature tact switches, aimed at design engineers developing home automation and Internet of Things (IoT) electronic devices. The PTS636 switch has a 6.0 x 3.5 mm footprint, and an adjustable thickness of 2.5, 4.3 and 5.0 mm while the PTS526 offers a 5.2 x 5.2 mm footprint and an adjustable thickness of 0.8 mm up to 2.0 mm.

The PTS526 and PTS636 switches are available in surface-mount packaging, and the PTS636 is additionally available in through-hole format, and use a hard actuator, ensuring that it can be fully integrated into standard processes, with no need for an additional interface button. The switches retain high reliability up to 500,000 cycles.

The PTS636 design includes a 2.5 mm height version with integrated ground pin while the PTS 526 design includes a version with integrated ground pin, with ESD protection soldered to the PCB. The PTS 636 is available in four different operating-force levels 130gf, 180gf, 250gf and 320gf, while customers of the PTS 526 can choose from three actuation forces: 160gf, 260gf and 320gf. Both sets of switches are rated at 50mA, has a bounce time of less than 10ms and an operating temperature range of -20 to +70°C.
