This type of spring, also known as an extension spring, works by resisting a pulling force. It absorbs and stores energy as it extends and then at a certain length, will create a return force and bring two components back to their original position. In their original, unloaded state, the adjacent coils will touch each other - however, the initial tension must be overcome before a tension spring extends.
