| [* black] What else changed? We think we spot some differences in the metal dome switches. The 2019 switch appears to have a slightly different color and surface finish than the 2018 version. | |
| - | [* black] This may be a result from a different surface treatment, or a completely different material |
| + | [* black] This may be the result of a different surface treatment or heat treatment, or a completely different material. |
| + | [* black] Any of these changes could help solve with the reliability issues plaguing the butterfly keys. |
| + | [* black] The dome is like a Snapple bottle cap—you press down and it springs back up. Like a Snapple cap, if you press too hard, crack it, or press it too many times, the cap will eventually stop popping back up. |
| + | [* black] The dome must reliably deform and pop back up every time a key is pressed. If anything changes about the dome—if it's cracked or deformed—the key may behave erratically. Likewise, if the two center prongs break off the key will stop working. |
| [* black] Surface treatment or alloy reformulation may strengthen the dome and prevent it from failing due to cracks, losing springiness, etc. | |
