Expanded IP67-rated tactile switch series features new options

Littelfuse, Inc. has expanded its NanoT tactile switch product line. The series, featuring miniature, surface-mounted, waterproof tactile switches, now incorporates new operational force options and top and side-actuated models, further improving its application in next-generation smart wearables, wireless headsets, portable medical devices, and IoT systems.

Design engineers need ever-smaller switch interfaces as the market demand for smaller, high-performance electronics increases – driven by innovations in healthcare, wearables, and battery-powered IoT devices. The expanded series is the smallest tactile switch solution on the market, providing design flexibility for engineers to integrate additional functionality or reduce PCB size.

"The NanoT switch combines space efficiency with high reliability, featuring short actuation travel, IP67-rated durability, and a wide operating temperature range from -40C to 85C," said Junbao Chen, design centre manager, Electronics Business Unit at Littelfuse. "Its ultra-compact size and ease of PCB/FPC integration make it ideal for confined spaces, while the haptic feedback ensures a satisfying user experience, optimising designs and improving product quality."
