摘要：
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.
