1. Material: Spring steel or stainless steel, save cost and with small volume.
2. Each spring features a variable pitch to achieve the constant spring rate and coils which nest during deflection to provide a solid height approximately equal to two wire diameters.
3. Shaped springs can reduced solid height.
4. Coil springs have Variable Rate.

Coil springs called compression springs can store mechanical energy when they are compressed. These open-coiled, helical springs provide resistance to compressive loading. When these springs are subjected to a compression load, they compress, grow shorter, and absorb a large amount of potential force.

The springs are forced back to their original lengths and forms after the load is reduced or eliminated by the stored energy. When weighted, compression springs become more compact. In contrast to extension springs, compression springs' spiral wires do not contact when they are relaxed; instead, when stressed, they are tightly compressed.

flat torsion springs

A Barrel Shaped Compression Springs is a type of Compression Springs used to produce linear force where the top and bottom outer diameter are smaller than the center outer diameter.  A barrel spring is chosen by end users over a generic compression spring mainly because it may reduce space, prevent buckling, and provide a multitude of shaped configurations to better fit in any designs.
