| 摘要 |
The invention relates to an input element, for example touchscreen, for electronic apparatuses, having a contact surface which can be moved in a translatory manner and interacts with an actuator, wherein the actuator is in the form of an electrostatic parallel-plate actuator the electrode plates of which are held at a variable normal distance in relation to one another, wherein the electrode plate which interacts with the contact surface can be deflected against the force of a restoring element, for example spring element, the electrostatic parallel-plate actuator has at least three electrode plates which are arranged one above the other and which are each held such that they can be deflected against the force of a restoring element relative to the electrode plate situated immediately therebeneath, that is to say the user can in this way receive, for example, tactile feedback when touching the touchscreen. Furthermore, parallel guidance for the electrode plate which interacts with the contact surface is provided. |
