| Point of purchase display |
 |
 |
Constant force springs have long extension capability, which ensures smooth linear movement, such as returning and retrieving. The feature is an important part of the design for point of purchase displays. When the cashier takes out the first pack of cigarettes vendor rack, the constant force of the spring pushes the rest of the cigarette packs ahead in the display rack, pack by pack.

| Applications of Constant Force Spring for Carbon Brush of Vacuum Cleaner |
 |
 |
Constant force spring is ideal for carbon brush of motor application, it can increase the life cycle of the brush.
Especially, vacuum machine and hand dryer, the rotating speed for these devices are very high; therefore, carbon brushes have to take a lot of wear and tear. The pretension of constant force spring is smaller than wire spring; as a result, there are two major advantages. Firstly, the outer diameter of the motor can be decreased. Secondly, a longer carbon brush can be adopted, so that a longer life cycle can be achieved.
Moreover, the other advantage of constant force spring is it can reduce EMI, because of the characteristic of constantly pressing brush against the commutator, which has better performance than the wire spring for electronic panel.
