    摘要: A data input device, such as a keyboard, comprising at least one key having a static electricity releasing circuit incorporated therein. The key comprises a manually operable keytop for pushing the membrane switch and is made from an electrically conductive plastic. At least one coil spring is provided between the keytop and the support panel or the other conductive layer that is connected to a ground. Thus a static electricity releasing circuit is formed from the keytop to the ground via the coil spring so as to instantaneously and reliably release static electricity that has accumulated on an operator to a ground.
