C&K switch targets medical IoT devices

Massachusetts switch maker C&K has introduced what it claims is the smallest switch on the market for applications powered by IoT devices, including smart watches and medical wearables such as health monitoring trackers and hearing aids.
 
The Nano Tactile (NanoT) is said to give designers of medical and wearable devices the freedom to create products as small as desired without forsaking quality and performance. A 2.2 by 1.70 by 1.65mm package gives designers the room to add additional functionality to their units or reduce PCB size.
 
A PIP or SMT on edge mount configuration protects wearable and medical products from the tough conditions they can be exposed to such as vibrations, accidental drops or exposure to liquid, while also improving the devices’ lifecycle since they are used repeatedly, which causes natural wear and tear.
 
An integrated actuator lowers cost and integration problems with full interface buttons.
 
Lifecycle is said to be up to 300,000. It is IP67 sealed for compatibility with PCB coatings.
 
“As wearable and medical devices continue to shrink, it’s critical that the switches used to keep them functioning properly fit within emerging size requirements,” said Jérôme Smolinski, senior product manager at C&K. “NanoT is the smallest tactile switch ever released in the market. This is not only a technical leap that keeps pace with the demand for sophisticated products that require smaller components, but it also provides easier and smarter design capabilities for our customers.”
 
C&K offers more than 55,000 standard products, 5.5 million switch combinations, as well as custom designed products, to help solve engineering problems in the automotive, industrial, IoT, wearables, medical, telecom, consumer products, aerospace and PoS terminal industries.
