The automotive, medical and industrial markets (among others) are always looking for smaller products that can fit on tight PCBs but are also reliable and efficient. For some applications, they need to be waterproof or fluid resistant to ensure that the product still works in difficult conditions. C&K's KMR Series was designed to fulfill stringent requirements and can be adapted to a wide range of applications.

The KMR Series is suitable for sensitive applications thanks to its premium quality. This product is available in various options and is customizable due to flexible manufacturing. The KMR Series' compact size (4,2 x 2,8mm) allow these switches to be fitted into applications where limited PCB space is available. These low profile tactile switches combine ultra-low current consumption and extended operational life. They are constructed with silver or gold plating, a tactile feel of more than 30%, and an optional ground pin. Two heights are also available: 1,9mm and 2,5mm. Various forces from 1,2 to 4N are offered for this series.
