The feel of a keyboard depends on the crucial ratio between the peak force (also known as the actuation force) and the contact force. Peak force occurs when you press down on the key and reach the maximum force that the key’s underlying rubber dome can withstand without deflecting. Contact force occurs when the bottom of the key touches the circuit board to trigger an electronic signal, which in turn generates the action appropriate to the key. To achieve the most natural feel for a keyboard, ASUS keyboard experts have scientifically determined that the optimal ergonomic click ratio for a key is between 45-60%. These forces are precisely measured and tuned using the ASUS-designed rubber domes beneath the keys.
