Abstract：
The invention discloses a wireless switch system comprising a wireless switch remote controller and a wireless switch device. The invention also discloses the wireless switch remote controller comprising a power supply, a signal generating module and a transmission antenna. The invention also discloses the wireless switch device comprising a switch, a reception antenna, an energy restoring moduleand a switch control module. In addition, the invention also discloses a communication control method of the wireless switch system. The communication control method comprises the following steps: thewireless switch remote controller emits a carrier energy signal, a modulated synchronous signal and an instruction data signal; the wireless switch device restores energy from the carrier energy signal; and according to judgment results of an identification code, a control code and a verification code, the wireless switch device outputs a control signal matched with a controlled switch so as to control the connection and disconnection of the switch. Therefore, holding state power consumption of an electronic apparatus with a remote control function can be completely eliminated, and the wireless switch system has a simple design and is easy to directly embed into the electronic apparatus with the remote control function.
