Micro-miniature Detect Switch Delivers 2 mm Overtravel
C&K Components has developed a micro-miniature, side-actuated, right angle detect switch in a low profile package. Designated the SDS Series, the detect switch sits 2 mm off the PCB while delivering 2 mm overtravel and a low actuation force of 75 g max. In addition to medical and consumer electronics, these detect switches are appropriate for detector applications in server blades, hot swap applications, copiers, smart card and PCB lock cam detection, and anywhere detecting the presence of a mechanical device is required. The SDS is frequently used in ATCA applications. Offered in SPDT-NO and SPDT-NC configurations, the side-actuated detect switch is available in right angle PCB-mount style. The switch features a long total travel of 2.0 mm. The SDS switch is available with either silver or gold contact and terminal plating depending on the application. The contact rating is 100 mA at 12 VDC, with a maximum contact resistance of 100 m-Ohm. Mechanical and electrical life is to 50,000 operations, and the operating temperature ranges from -40°C to +85°C. The switches are pick and place compatible and available in bulk or tape and reel packaging (3,000 pieces per reel). Typical pricing for the SDS Series micro-miniature side-actuated detect switches ranges from $0.44 to $0.46 each in quantities of 12,000 pieces.
