Compression Springs

A compression spring is an elastic coil, made of spring steel - its spring characteristic is that it absorbs force or provides resistance.

A compression spring can be used as a pure energy accumulator, shock absorber, vibration damper or force generator.   

The commonest type of metal spring, they are very effective at building up energy, and therefore have countless potential applications. The compression spring has gaps between its coils in an unloaded state. The distance between the coils is reduced when the spring is loaded and compressed. 

In principle, a compression spring must never be compressed so much that the coils touch one another. This shortens the service life of the spring considerably.

You’ll find compression springs in tools, industrial equipment, pens or notebooks, many toys and things like mattresses.
