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.
