Abstract
A key button structure for entering data in an electronic device comprises a first key element and a second key element. The second key element is retained to the first key element by a retaining mechanism. The second key element has a joint positioned at a side thereof opposite to the first key element and two actuators located at an opposite side thereof facing the first key element. The joint pivotably couples the second key element to a housing of the electronic device.
Claims19
A key button mechanism for entering data in an electronic device, comprising:
- a first key element;
- and
- a second key element retained to the first key element by a retaining structure, the second key element having a joint positioned at a side thereof opposite to the first key element and two actuators located at an opposite side thereof facing the first key element, the joint pivotably coupling the second key element to a housing of the electronic device,
- wherein the joint is located at a center of the second key element and the two actuators are located at two opposite ends of the second key element,
- wherein both the first key element and the second key element pivot together about the joint.
An electronic device, comprising:
- a housing;
- a printed circuit board mounted to the housing;
- and
- a key button mechanism comprising:
- a first key element;
- and
- a second key element retained to the first key element by a retaining structure, the second key element having a joint positioned at a side thereof opposite to the first key element and two actuators located at an opposite side thereof facing the first key element, the joint pivotably coupling the second key element to the housing;
- wherein the printed circuit board is located between the first key element and the second key element, the printed circuit board further includes two domes located on a side of the printed circuit board facing the second key element corresponding to the actuators of the second key element,
- wherein the joint is located at a center of the second key element and the two actuators are located at two opposite ends of the second key element,
- wherein both the first key element and the second key element pivot together about the joint.
An electronic device, comprising:
- a housing;
- a printed circuit board mounted to the housing, the printed circuit board having two domes spacedly mounted thereon;
- and
- a key button mechanism comprising:
- a first key element;
- and
- a second key element retained to the first key element, the second key element having a joint positioned at a side thereof opposite to the first key element, the joint is pivotably coupled the second key element to the housing;
- wherein the printed circuit board is located between the first key element and the second key element, the second key element further includes two actuators located on a side thereof facing the printed circuit board, when the first key element is pressed, the first key element and the second key portion are rotated about the joint relative to the housing and the printed circuit board so that an actuator of the second key element pushes down a corresponding dome wherein the joint is located at a center of the second key element and the two actuators are located at two opposite ends of the second key element,
- wherein both the first key element and the second key element pivot together about the joint.
