scissorlüliteid

Scissorlüliteid, also known as scissor switches, are a type of electromechanical switch commonly found in keyboards and other input devices. They utilize a scissor-like mechanism to connect and disconnect electrical contacts. This mechanism consists of two hinged plastic or metal pieces that resemble a pair of scissors, which open and close to activate the switch.

The primary advantage of scissor switches is their low profile and stability. The scissor mechanism prevents the keycap from wobbling excessively, providing a more consistent typing experience. This design allows for thinner keyboards compared to those using traditional mechanical switches. When a key is pressed, the two parts of the scissor mechanism pivot, pushing down a rubber dome or a plunger that actuates the electrical contact beneath. Releasing the key causes the mechanism to return to its original position.

Scissor switches are known for their relatively quiet operation and tactile feedback, although the exact feel can vary depending on the manufacturer and specific implementation. They offer a balance between the distinct feel of mechanical switches and the quietness of membrane keyboards. This makes them a popular choice for laptops and compact keyboards where space and noise are considerations. The durability of scissor switches is generally good, with many rated for millions of keystrokes.
