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.

Variations

1st-gen

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

2nd-gen

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]
