Spring contact connectors come in 13 types

HARWIN Spring Contact Connector range includes 13 new models including extended C and Positive Stop models in  nine different heights, ranging from 4.5mm down to low profile designs of 1.1mm above board level, enabling smaller, lighter, low-profile pcb designs to be achieved. Devices maintain a positive force against a mating surface and are available in different widths to offer a choice of spring contact forces. Tolerant to significant mating misalignment, products incorporate ‘positive stop’ to prevent damage caused by over compression. A contact anti hook up feature is a further benefit. http://www.harwin.com
