Detect switches protect ATCA boards

Increasingly employed on advanced mezzanine cards for improved data integrity in military, datacomms and medical applications.

C+K Components has developed a variety of detect switches for use in ATCA (Advanced Telecom Computing Architecture) applications.

The MDS Series, SDS Series, SDT Series and HDT Series detect switches are implemented on the server blade as a safety mechanism to guarantee the blade is powered down, while ensuring no data are lost.

"Switches in ATCA applications have traditionally been through-hole mounted, but we have added a full line of surface mount products, providing our customers with greater design flexibility and allowing us to extend the terminals to provide a more robust assembly to the PC board", says David Webber, Senior Product Manager for C+K Components.

"The extended offering of detect switches allows us to meet the expanded temperature ranges and vibration requirements as ATCA applications continue to grow in popularity in the military and medical arenas".

Whereas most ATCA applications are used in network and telecomms servers, the detect switches are also being increasingly employed on advanced mezzanine cards (AMC) for improved data integrity in military, datacomms and medical applications, including black boxes and high-end ultrasound equipment.

The family of detect switches comprises: the MDS Series of micro snap-acting detect switches available in vertical and right-angle PCB mount, with 2.9mm travel; the SDS Series of side-actuated detect switches with low 2mm profile and 2mm overtravel; the SDT Series of micromini pendulum detect switches with top or side actuation and low 3.3mm profile; and the HDT Series of micromini detect switches with top or side actuation and low 3.35mm profile.
