Tapered Spings

Tapered springs are also known as conical springs. This name comes from its shape since the term tapered means to reduce in thickness toward one end. As you can see a tapered / conical spring is just that, a spring with coils that are reduced in shape as they coil and form a cone structure.

This allows the user to compress the spring all the way down so that all the coils of the spring collapse inside themselves down to one wire diameter (the thickness of one wire) which provides more travel or deflection. This is ideal when the creator of a product requires the spring to have more deflection (the distance the spring has deflected or compressed) but there is not enough space for a longer spring.
