Back in 2017 in our meeting with Seimitsu, we discussed and suggested the idea of having different tensions for their pushbuttons by using different springs

This was first implemented in their PS-14-K pushbuttons in 2018, which we have carried ever since

You can now purchase these springs separately and install them in your existing PS-14-K or PS-14-KN pushbuttons in two different tension types

The stock PS-14-K or PS-14-KN pushbutton has a tension of 1.0N

Choose between two additional tensions that add .25N or .50N of force to your pushbutton
