Sub-miniature tact switch targets IoT in the home

Electromechanical switch manufacturer, C&K, has introduced a sub-miniature PTS815 tact switch aimed at design engineers developing home automation and IoT electronic devices.

It has a footprint of just 4.2 x 3.2mm and is 2.5mm thick to save space in designs with limited space and frees up board space for other components to be added.

With a large actuation surface for easier integration, the switch is suited to applications such as home automation, IoT devices and e-cigarettes, as well as control systems for items such as drones, e-bikes and robot vacuum cleaners.

The PTS815 is manufactured in surface-mount technology (SMT) format and uses a hard actuator, ensuring that it can be fully integrated into standard processes, with no need for an additional interface button, reducing time and costs for the end equipment manufacturer.

It is available in the versions most commonly used by the market to meet the needs of many commercial applications, while retaining rigid quality control. The PTS815 retains high reliability at over 100,000 cycles, reports C&K.

According to the company, the PTS815 offers easier integration due to its variable range of force before the actuator is tripped, audible click from the hard actuator and large actuation surface.

Three operating-force levels are available: 180gf, 250gf and 400gf. The PTS815 switch is rated at 50mA, has a bounce time of less than 10ms and an operating temperature range of -20 to +70 degrees C.

The PTS815 is now available to OEMs.

Founded in 1928, C&K produces electromechanical switches and has custom design capabilities. C&K offers more than 55,000 standard products and 8.5 million switch combinations to companies that design, manufacture and distribute electronics products. Used in automotive, industrial, IoT, wearables, medical, telecomms, consumer products, aerospace and point of sale terminals, C&K products include tactile, pushbutton, snap-acting, toggle, rocker, detect, DIP, keyswitch, navigation, rotary, slide, switch lock, thumbwheel, smart card readers, high-rel connectors and custom assemblies.
