PROBLEM TO BE SOLVED: To carry out quick switching control with a wireless switching controller that controls a switch by a radio signal. SOLUTION: The wireless switching controller includes: an antenna for receiving radio signals; a SAW correlator that detects a signal modulated with a specific coding pattern, from radio signals received by the antenna and outputs detection voltage; and a switching control unit that controls a switch, based on the detection voltage of the SAW correlator. The switching control unit includes the movable electrode and the fixed electrode of an electrostatic attraction-driven MEMS switch and applies the detection voltage of the SAW correlator to between the movable electrode and the fixed electrode and drives the electrostatic attraction-driven MEMS switch by electrostatic attraction, produced between the movable electrode and the fixed electrode by the detection voltage.
