Abstract
A keyboard switch actuates a switch sheet from a first position to a second position and correspondingly narrows a gap between a key top and the switch sheet. In keyboard switch operation, trailing claw pieces cause a cross-link to submerge allowing the switch sheet to accommodate an integrally formed return springwithout elastic deformation.
