More Information
Summary:A key structure includes a membrane switch circuit member, a rubbery elastomer, a housing, a triggering element, a metallic elastic element and a keycap. The keycap is disposed on the triggering element. The rubbery elastomer is disposed on the membrane switch circuit member. The housing is located over the rubbery elastomer. The triggering element is movable relative to the housing. The metallic elastic element is contacted with the triggering element. While the keycap is depressed, the triggering element is moved relative to the housing to press the metallic elastic element. While the metallic elastic element is pushed by the triggering element, the metallic elastic element is swung to collide with the triggering element. Consequently, a click sound is generated.
