C&K Components has developed a microminiature surface mount detect switch. Designated the HDT Series, the switch sits just 3.5mm off the PC board and is designed for both top and side actuation.
"With an extended temperature range and long electrical and mechanical life, the HDT Series detect switch is ideal for Advanced Mezzanine Card (AMC) applications," said Worldwide Product Manager for C&K Components. "This detect switch is currently implemented as a reference design for the handle mechanism on AMC cards." AMC product standards are designed to support ATCA and MicroTCA systems that are being increasingly employed in telecommunications, server, medical and military applications.
The HDT Series microminiature detect switch features a long operational life of 100,000 cycles. Maximum actuation force is only 35 grams. Pre-travel is 0.30mm with over-travel of 0.75mm. Maximum contact resistance is 500mohms, with a maximum contact rating of 1mA at 5VDC. Operating temperature ranges from -40°C to +85°C. The switches are pick and place compatible and available in tape and reel packaging.
