Scissor-switch

Also known as: scissor switch, scissor-stabilised rubber dome, pantograph switch
A scissor-switch is a rubber dome keyswitch design where their keycaps and keyboard frame are connected via two cross-arms designed to stabilise the key. The domes on such keyswitches are typically very small, thus they can struggle to stabilise a key on their own, requiring the scissor structure to ensure a more uniform travel regardless of where you press the key and reduce wobbling. They are typically used for low-profile applications such as laptop keyboards, but various desktop keyboards such as IBM's and Lenovo's SK-8835, SK-8840 & SK-8845 family and Apple Magic Keyboard family also use them.
