I am very aware that for our best switch, we also need to consider its placement. The surface or component it sits on plays a big role in its optimal functioning, as well as its location within the home network. What’s upstream and downstream from the switch matters too—each aspect contributes to its overall performance.
Just my two cents on isolation platforms: In audio, they are used to prevent external vibrations from reaching a device or to redirect vibrations generated by the device itself. Platforms and footers can also be used to fine-tune the sound (including for switches), but I’ll leave that discussion for another time.
For a switch, focusing on preventing incoming vibrations—if that's the issue—is key. Non-damped compression springs, however, are unlikely to be as effective in this case. They can act as mechanical resonators, absorbing energy but potentially allowing vibrations to persist or even amplify. Without damping, the springs might cause the switch to oscillate or bounce.
To get audible results, you might want to explore damping materials that help absorb and dissipate energy more effectively, or consider changing your isolation strategy to better stop vibrations from reaching the switch. Also, it would be helpful to understand what kind of vibrations you're trying to eliminate. Are they from living next to a highway, your speakers, wood floors, or a wood beam construction?
