C&K has launched two subminiature tactile switches that feature a large actuation surface for easier integration and are aimed at home automation and other designs built around internet of things (IoT) applications. The ultra-compact PTS636 and PTS526 tact switches can also be used in control systems for drones, e-bikes, and robot vacuum cleaners.
The PTS636 switch has a 6.0 × 3.5-mm footprint and an adjustable thickness of 2.5 mm, 4.3 mm, and 5.0 mm. It is available in four different operating-force levels: 130 gf, 180 gf, 250 gf, and 320 gf. The PTS526 tact switch offers a 5.2 × 5.2-mm footprint and an adjustable thickness of 0.8 mm to 2.0 mm. It offers three actuation forces: 160 gf, 260 gf, and 320 gf.
The PTS636 and PTS526 offer reliability of up to 500,000 cycles. Both switches are rated at 50 mA and offer a bounce time of less than 10 ms. The operating temperature range for both lines is −20°C to 70°C.
C&K’s tact switches are manufactured in surface-mount technology (SMT) format, and they use a hard actuator to ensure that switches can be efficiently integrated into standard processes. That eliminates the need for an additional interface button, thus reducing costs as well as time to market.
The PTS636 design includes a version with 2.5-mm height and an integrated ground pin, while the PTS526 design includes a version with an integrated ground pin. The tact switches also facilitate easy routing of unwanted electrical overload with electrostatic discharge (ESD) protection soldered into the printed circuit board.
