The tactile switches offer space-saving designs, customizable force options, and durability for wearables, medical devices, and IoT systems applications.
Littelfuse, Inc. has announced the expansion of its NanoT tactile switch product line. This series of compact, surface-mounted, waterproof tactile switches now includes additional operational force options and both top- and side-actuated models. These enhancements make the NanoT series ideal for next-generation applications such as smart wearables, wireless headsets, portable medical devices, and IoT systems.
The company claims the tactile switch product line suits applications like smart wearables, health monitoring devices, hearing aids, wireless headsets, and portable IoT devices.
As demand for smaller, high-performance electronics continues to rise—driven by innovations in healthcare, wearables, and battery-powered IoT devices—design engineers face increasing pressure to create compact switch interfaces. The expanded NanoT series addresses this need by offering the smallest tactile switch solution available, enabling greater design flexibility to integrate additional functionality or minimize printed circuit board (PCB) size.
A few Key Benefits of the NanoT Series include:
- Space-saving design: Ultra-compact for more functionality or smaller PCBs
- Customizable actuation forces: 100, 160, 240 gf options
- Mounting options: PIP or SMT edge-mount for shock resistance
- Durability: 200K to 300K life cycles for long-term reliability
- IP67 rating: Dust-tight and waterproof for tough environments
“The NanoT switch combines space efficiency with high reliability, featuring short actuation travel, IP67-rated durability, and a wide operating temperature range from -40°C to 85°C,” 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, optimizing designs and improving product quality.”
