Conical compression springs are cone shaped to provide near constant spring rates and significantly more travel or lower solid height than traditional compression springs. Because of the tapered shape these springs can be referred to as tapered springs. The improved solid height is achieved by nesting active springs within each other during compression. A common application for a conical spring is in electrical contacts, such as battery contacts and push buttons. Stock springs are supplied with ends squared and right hand wound.
