Apple butterfly mechanism is mechanism for a type of scissor switch where the hinge is made of rubber double-shot moulded with the legs. This single-part design improves stability and reduces thickness for extremely low-profile keyboards compared to mechanical hinges.



Apple is using this mechanism along with a stainless-steel dome switch on the MacBook (Retina, 12-inch, Early 2015).[1]


The 2016 MacBook Pro (13 and 15-inch, with or without touch bar) come with an updated mechanism.[2] The keys are taller at the edges making them easier to find by feel. The metal dome is heftier and mounted to the keycap.[3]


The MacBook keyboards are infamous for bad reliability.

According to an article in AppleInsider magazine, the 2016 MacBook Pro keyboards fail twice as often in the first year of use as previous types of MacBook Pro keyboards that have a more conventional scissor switch/rubber dome design.
