New Series of miniature, low profile, SMD Tactile Switches for Wearable and Portable IoT Devices

7 December 2022 - 0 Comments

Littlefuse has announced the new C&K Switches NanoT product line, a series of miniature, surface-mounted, very low profile, waterproof tactile switches. Smart wearables, health monitoring devices, and other battery-powered IoT devices are driving the need for a higher density of active components integration, seamless rounded screens, and additional functions in increasingly smaller spaces. The result is a demand for the switch interface to be smaller and smaller. The new NanoT switch series is the smallest tactile solution on the market. It gives product designers room to build additional functionality into their design or reduce their printed circuit board (PCB) size.

The NanoT is ideal for use in a wide range of wearable and portable consumer electronics, including:

Hearing aids,
Health-monitoring devices,
Smartwatches,
Portable IoT devices, and
Headsets.

NanoT Tactile switches Features

Ultra-compact size enables designers to add functionality or reduce PCB size, providing significant space-saving over other solutions on the market.
- Side-actuated package (2.2 x 1.70 x 1.65 mm) saves 35%.
- Top-actuated package (2.1 x 1.65 x 0.55 mm) saves 20%.
PIP or SMT edge-mount versions allow excellent resistance to shock and shear testing, improving equipment lifetime while reducing layers of protection.
Life cycles up to 300K offer greater reliability, reducing the chance of costly repairs.
IP67 provides end-user customers with the high reliability of waterproof functionality.
Operation force options of 100, 160, and 240 gf provide the most common versions required by the market.
