11 myths about electromechanical tactile switches.

1. Switches are a normalized commodity. The saying “no two snowflakes are alike” also applies to switches. Unlike connectors in which male/female coupling can be possible, even if the two components are from different origins, there’s no industry standard mandating uniform design, form factor, or behavior when it comes to switches. As a result, each switch manufacturer has total freedom to define its design, select raw materials, and target different performance criteria or market needs (e.g., high-end industrial vs. low-cost toy market). 2. The same form-factor switches from various manufacturers are all the same. The devil is in the details! Even pin-to-pin compatible, or side-by-side comparable, tactile switches can create different functionalities and perhaps different user perception on how they should work. In any case, the mechanical equivalence doesn’t automaticall...
