Littelfuse introduces the minimum IP67 touch switch

Littelfuse Corporation has announced the launch of its new C&K Switches NanoT product line, which consists of micro, surface-mounted, extremely small, waterproof tap switches. Smart wearables, health monitoring devices and other battery-powered iot devices are driving demand for higher density active component integration, seamless circular screens and additional features in ever-smaller Spaces. As a result, the interface of the switch is required to become smaller and smaller. The new NanoT switch family is the smallest light-touch solution on the market today. The system provides product designers with the space to add additional features to their designs or reduce the size of printed circuit boards (PCBS). Watch the video.

NanoT is ideal for use in a variety of wearable and portable consumer electronics including:

● Hearing AIDS,

● Health monitoring equipment,

● Smart watches,

● Portable iot devices, and

● Headphones.

"We are excited to release the NanoT switch, the world's smallest light-touch solution available today for high-end portable, wearable consumer and medical applications." Says Daisy Liu, global product manager of C&K Switches, a unit of Littelfuse. "The series offers the IP67 waterproof tap switch in the smallest size. Surface Mount Technology (SMT) reflux process is used for top-mount versions, and pin solder paste (PIP) reflux process is used for side-mount versions. As a result, this product meets the market demand for smaller components, while providing our customers with the ability to achieve high quality and high performance in their latest designs."

NanoT has the following main advantages:

● The ultra-compact size allows designers to add functionality or shrink the PCB size, saving a significant amount of space compared to other solutions on the market.

○ Side operation package (2.2 x 1.70 x 1.65 mm) saves 35%.

○ Top operation package (2.1 x 1.65 x 0.55 mm) saves 20 percent.

● PIP or SMT edge mount versions have excellent impact and shear testing capabilities, extending device life while reducing protective layers.

● Life cycle of up to 300K provides increased reliability and reduces the number of expensive repairs.

● IP67 provides high reliability waterproof function for end-use customers.

● The 100,160 and 240 gf operating force options offer the most common versions required by the market.
