Smallest IP67-Rated Tactile Switch Available

Littelfuse, Inc., an industrial technology company that powers a sustainable, connected, and more secure world, announces its new product line of C&K Switches NanoT, 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 higher density active component integration, seamless rounded screens, and more functions in smaller spaces. The result is a need for switch interfaces that are smaller and smaller. The new NanoT switch series is the smallest tactile solution on the market. This gives product designers room to build more functionality into their design or reduce their printed circuit board (PCB) size.

NanoT is ideal for use in a wide range of wearable and portable consumer electronics,
including:
 Hearing aids
 Health monitoring tools
 Smartwatches
 Portable IoT devices
 Headsets

“We are excited to release the NanoT switch, the world’s smallest tactile solution available today for high-end portable, wearable consumer and medical applications,” said Daisy Liu, Global Product Manager of C&K Switches, now part of Littelfuse. “They provide the smallest size, IP67 waterproof tact switch available. They use surface-mount technology (SMT) reflow process for the top version and Pin-in-Paste (PIP) reflow process for the side version .As a result, this product meets the market demand for small components while giving our customers the ability to provide high quality and high performance in their latest designs.

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

NanoT is available in tape and reel format in quantities of 8,000 pieces for the top version and 7,500 for the side version.
