A flat, spirally wound spring used to provide a restraint for rotary motion of a shaft. Hairsprings are used in D’Arsonval-type electrical instruments to provide a calibrated restraint for the moving coil and to carry current into and out of the coil. Hairsprings are also used in spring-powered clocks and watches to regulate the movement of the balance wheel.

A flat, spiral-wound spring made of two strips of metal laid side-by-side and welded together. The two metals have different coefficient of expansion, and as the temperature changes, the spiral either tightens or loosens. The pointer of an analog thermocouple-type temperature indicator is mounted on a bimetallic hairspring to compensate its indication for changes in temperature of the reference junction.
