摘要:
A keypad apparatus and related methods are disclosed herein. An example keypad apparatus includes an electrical switch and a carrier composed of a plastic resin. The carrier has conductive traces printed thereon to couple the electrical switch to a circuit board via interference.

A keypad includes discrete keys formed by touch sensors or virtual keys on a touch sensitive area. The discrete or virtual keys are mechanically linked to a biased switch. The key that has been touched during a keystroke is identified through a signal from the touch sensors whilst a keystroke is recorded upon a signal from the biased switch. The combination of the touch sensors with a biased switch provides tactile feedback. The use of touch sensors or a touch sensitive area allows the keypad to be constructed with a substantially flush surface without parting lines.

A keypad includes a light guide panel, the interior of which light propagates through, a film positioned on the upper surface of the light guide panel and having at least one key button positioned on the upper surface thereof, and at least one reflective pattern fixedly positioned with respect to the light guide panel to reflect a part of the light, which propagates through the interior of the light guide panel, towards the key button.
摘要:
An improved handheld electronic device and method provide an input apparatus having a number of input members, at least a portion of the input members being movable among an unactuated position, a first actuated position, and a second actuated position in order to provide input. The improved method of enabling input into the handheld electronic device includes detecting a first input from a first input member, responsive to the first input, performing a first navigational function, such as a scrolling operation, at a first speed, detecting a second input form the first input member and, responsive to the second input, performing the first navigational function at a second speed, the second speed being different (e.g., greater) than the first speed. The input apparatus may include a substantially sealable, resilient membrane with the input members being disposed on the resilient membrane in order to provide an improved, ruggedized input apparatus.

摘要:
To substantially prevent debris from entering the internal volume of a dome switch, the dome switch can be configured to include limited or no external vents. However, to ensure that the air can be displaced and to avoid an excessively high pressure underneath the dome with the dome is inverted, the dome switch can include one or more internal regions for receiving the displaced air. In particular, the dome switch may include one or more integrated reservoirs. For example, the integrated reservoirs can be placed in a layer between a film placed over the dome and a circuit board on which the dome is placed. As another example, the integrated reservoirs can be constructed out of the plane of the circuit board.
