Abstract: A touch input device which detects a touch position and a touch pressure magnitude may be provided that includes: a display module; a first electrode and a second electrode which are disposed on the display module and are spaced apart from each other; a spacer layer which is formed on the display module and covers the first electrode and the second electrode; and a transparent ground electrode which is disposed on the spacer layer and is formed of a material having transparency. A distance between the transparent ground electrode and the display module is changed by inputting a touch on the transparent ground electrode, and a capacitance between the first electrode and the second electrode is changed by the distance change. The position of the touch and the pressure magnitude of the touch are detected based on the changed capacitance.

Abstract: Provided is an electrostatic drive switch, which includes a source plate to which a voltage for driving the electrostatic drive switch is applied and a drain electrode spaced apart from the source plate. The source plate includes a source electrode and an elastic part connected to the source electrode, and a first material and a second material having lower hardness than the first material are provided on the source electrode. When the source electrode and the drain electrode are electrically connected to each other by the voltage, the second material is brought into contact with the drain electrode by the elastic part after the first material is brought into contact with the drain electrode by the elastic part.
