Abstract
A closed-air cushioned key switch structure includes an electrical board having multiple contacts, and multiple key switch bodies arranged above the contacts of the electrical board, each key switch body having top press portion for clicking by a user, a conductor at the bottom side for contacting one respective contact of the electrical board to produce a switching signal and an enclosed air chamber defined in between the press portion and the conductor for buffering clicking to give comfort to the user's finger to avoid noises. The key switch bodies are formed in integrity without any gap in therebetween, avoiding penetration of fluid or water through the key switch bodies to contaminate or wet the electrical board.
Claims9
A closed-air cushioned key switch structure, comprising:
- an electrical board, said electrical board comprising a circuit layout arranged thereon and at least one contact located on said circuit layout;
- and
- at least one key switch body arranged above said electrical board, each said key switch body comprising an enclosed air chamber, a press portion formed of a top wall of said enclosed air chamber for clicking by a user, and a conductor located on a bottom side of a bottom wall of said enclosed air chamber and adapted for contacting one said contact of said electrical board to produce a switching signal when a user clicks the press portion of one said key switch body.
A closed-air cushioned key switch structure, comprising:
- an electrically insulative panel frame;
- an electrical board fixedly mounted inside said electrically insulative panel frame, said electrical board comprising a circuit layout arranged thereon and at least one contact located on said circuit layout;
- at least one key switch body arranged above said electrical board, each said key switch body comprising an enclosed air chamber, a press portion formed of a top wall of said enclosed air chamber for clicking by a user, and a conductor located on a bottom side of a bottom wall of said enclosed air chamber and adapted for contacting one said contact of said electrical board to produce a switching signal when a user clicks the press portion of one said key switch body;
- and
- a cover shell fastened to said electrically insulative panel frame and covered over said at least one key switch body, said cover shell comprising at least one aperture for enabling the passing of the press portion of each said key switch body.
