1. Scope of application

This product is suitable for mobile phones with flip function, or other related products that need to achieve flip action. In order to realize the mechanical flip function of related products.

2. Product appearance

2.1 For detailed outline dimensions and materials, please refer to the "Product Assembly Dimensions" at the back.

2.2 The appearance must not show any scars that affect the size and mechanical properties of the product.  

3. Mechanical performance

3.1 Initial elasticity (or torque—Torque. Unit: Kgf.Mm. Tolerance: ± 0.5)

2.0  | 3.0 | 3.5 | 4.0 |  4.5 | 5.0 | 5.5 | 6.0 | 6.5 | 6.8  | 7.0 | 7.5

                                                        ∨

The initial elasticity can be adjusted appropriately according to customer requirements, and the product dimensions have nothing to do with elasticity.

Note: The greater the elasticity, the greater the negative impact on the life of the shaft. At the same time, the greater the elastic force, the larger the diameter of the spring wire and the greater the height of the loop, the more difficult it is for the exposed plastic head of the shaft to be pressed to the bottom, which will seriously make it difficult to install the shaft into the casing.

3.2 Service life (unit: ten thousand times): 

3.0  |  4.0  |  5.0  |  6.0  |  7.0  |  8.0  |  9.0 |  10.0  |  11.0  |  12.0 

                                                                      ∨

3.3 Rotation angle: 

0°～ 180°～ 360° 

Elastic balance point (also called "dead point")

Location: 90 °±10° 

The rotation axis can be rotated freely in CW and CCW directions.
