C&K expands SDS Series with Ultra Low Current option

C&K, a leading manufacturer of high-quality electromechanical switches, has extended its detect product family to include a new ultra-low current variant. The SDS Ultra-low Current detect switch was developed to limit power consumption on battery powered devices.  With more and more devices being operated by battery, designers are looking to solutions that consume as little energy as possible to prolong battery life.

SDS series is available with different contact arrangements, normally open, normally close, silver and gold plating for better resistance of the corrosion. The ultra-low current (10µA@1.8VDC) option enriches the catalogue options well in the related application of medical & IoT devices, smart metering, smoke detector and Networking. 

For applications like medical and IoT devices this product has been tested and proven to reduce battery consumption.  Offering a ultra-low profile switch with low battery consumption makes the SDS ideal for handheld devices.

C&K offers the SDS with overtravel plunger actuator which allows for 2mm of overtravel. “With the growing production of devices using battery power, we have developed an ultra-low current switch to fit market needs” explained Cedric Garropin, Product Manager at C&K. “By reducing necessary current to operate this switch, battery consumption triggered by an actuation is heavily reduced compared to other switches.”

The entire line of SDS Series detect switches feature a SPST design, 50,000 cycles, 75gf actuation force, and right angle termination. The switches’ low 2mm PCB-mounted profile makes them ideal for designs with limited space above the PCB.
