Rückstelldrehfeder

A Rückstelldrehfeder, often translated as a reset spring or return spring, is a mechanical component designed to exert a force that returns a mechanism or part to its original or a predetermined position. These springs are commonly used in situations where a component is moved out of its resting state and requires a reliable force to bring it back. The operation of a Rückstelldrehfeder relies on the elastic properties of the material from which it is made. When the spring is deformed, it stores potential energy, which is then released to create the return force.

The design of a Rückstelldrehfeder can vary significantly depending on its application. They are often made of spring steel or other resilient alloys. The torque or force exerted by the spring can be precisely engineered by controlling its dimensions, material properties, and the amount of initial tension. Common examples of their use include the return mechanism for levers, pedals, switches, and various types of latches. In automotive applications, they might be found in ignition switches or certain control mechanisms. The term "Rückstelldrehfeder" specifically implies a spring that provides a rotational return force, distinguishing it from linear return springs. Their reliable and consistent performance makes them a fundamental element in many engineered systems.
