C&K Components has developed a series of low profile tactile switches that combine ultra-low current consumption and extended operational life. Designated the KMR Series, the switches feature an operating current of only 1µA at 1.8VDC, actuation forces to 4N and a life span to 300,000 cycles, making them ideally suited for mobile applications.

“The surface mount tactile switches are capable of extending the life of our customers’ products,” said Jerome Smolinski, senior product manager for C&K Components. “With reduced power consumption, the switches can extend the battery life in various applications, which is particularly beneficial in portable electronics such as automotive keyfobs.”

In addition to automotive keyfobs, the KMR Series microminiature switches are specified for use in cellular phones, industrial electronics and medical equipment. The KMR 2 switches sit 1.9mm high and feature an actuation force of 1.2N to 4N, while the KMR 4 devices are 2.5mm high with an actuation force of 2N to 4N. The switches are constructed with silver plating (gold is available upon request), a tactile feel of more than 30%, and an optional ground pin. Both models have a footprint of 4.6mm x 2.8mm.
