Custom membrane switches and potentiometers

Google Ads in it’s infinite wisdom suggested to me the Spectra Symbol company, which lets design custom membrane switches and potentiometers. DIY synth and Circuit bending implications of these pads and switches are countless, especially when used with a microcontroller. No costs are mentioned on the website, my guess is that it can be expensive, but they do offer free samples. I ordered some so we’ll see what happens.
