5 Places Flat Springs are Found

A flat spring has a different use than coiled springs. Flat springs contain the tension of the spring in a winding pattern that eventually released. Flat springs were originally used in clocks, and today have uses in a variety of products from timers to parking meters. In everyday life, you will find flat springs in a variety of places, such as:

Scales: Many scales use flat springs to control the movement of the scale hands that measure the weight of an object. Simple scales like grocery store scales, and more complex scales, like bathroom scales use the same kind of spring mechanisms inside the unit to control the pieces of the scale.

Clocks: Flat springs are ideal for use with clocks because they tighten and loosen according to the pressure applied to the spring. The spring unwinds to power the clock and move the clock hands. When the spring is spent, it can be wound again to power the clock once more.

Timers: Timers use flat springs similarly to how clocks use them. The timer is activated and unwinds the spring. When the spring is unwound, the timer goes off. Winding the timer again tightens the spring and prepares it for the next round of timing.

Car suspension: Flat leaf springs are an important part of car suspension. If a vehicle does not use a coil suspension, then it often uses flat spring suspension. The springs absorb the shock from the wheels and help protect the car from bumps, jolts, and other problems on the road.

Stove knobs: Stove knobs also use a flat spring to control the heat of a stove. The springs keep the knobs from turning too easily. The springs also make the “click” sound that you hear when you turn the stove off. That sound is the release of the spring that keeps the stove from turning on accidentally.
