This kind of connection is used in cases where permanent connection techniques like soldering or non-permanent ones like pogo pins or elastomeric "Zebra" connectors are not suitable, for example due to extreme vibrations or temperatures. They can also be used where low-distortion signal transmission is needed, like on PCB (board-to-board) interconnects, or in IC testing sockets where additionally many mating cycles are required.
