Claim Text:
1. A microelectronic switch, comprising: a gate electrode; a source electrode; a drain electrode; a first electrostatic electrode electrically connected with a common electrode line; a cantilever with two working positions of an open position and a closed position; a connecting portion arranged at a side of the cantilever facing towards the source electrode and the drain electrode wherein the connecting portion is electrically connected with the source electrode and the drain electrode when the cantilever is in the closed position; a second electrostatic electrode arranged on a surface of a side of the cantilever facing towards the first electrostatic electrode, the second electrostatic electrode being electrically connected with the gate electrode and arranged opposite to the first electrostatic electrode; an insulating dielectric layer arranged between the first electrostatic electrode and the second electrostatic electrode, wherein the cantilever is located at one working position of the two working positions when the voltage applied by the gate electrode to the second electrostatic electrode is less than a preset threshold, the first electrostatic electrode and the second electrostatic electrode attract each other so as to enable the cantilever to be switched to the other working position of the two working positions when the voltage applied by the gate electrode to the second electrostatic electrode is greater than the preset threshold.
