SPRiT  MX  Progressive Springs     

 

-   World Premier Oct  2018 

-   Challenging to 99% Supreme Precision - avrg 0.5g variance  

- Made in Korea of the premium materials     

  

I have designed  Progressive rate springs to be much lighter than the conventional springs by 8g - 10g until the actuation point as Graph 1.   

The force rises rapidly after actuation, results in the same bottom out weight as the linear springs.  If you want to experience bouncier bottom out, please try one or two level heavier springs. 

Progressive springs are hard to find any practical example in the electronics industry, the production is trickier and takes much longer time.

 

* No Polarity on Progressive springs.

  According to the Newtonians,   Fab  =  - Fba  

 

  You can say this simply,  "When you press the lighter end, the heavier end will be pressed by exactly the same pressure. vise versa."    or 

   "It damn doesn't matter, which end.  You feel the pressure exactly by the pressure you press."

 

Please Enjoy Your Premier Builds
