Abstract: An apparatus having a passive wireless switch is provided. The apparatus includes a device system, a device switch, a passive wireless switch, and an antenna module. The passive wireless switch includes a microprocessor, a discrete signal-outputting unit, and a charge module. When the charge module is charged to enable the micro-processor by receiving a radio frequency wireless electric wave, the micro-processor may match an identification code contained in the RF signal with the identification code of the passive wireless switch. If the identification code contained in the RF signal is the same as the identification code of the passive wireless switch, the discrete signal-outputting unit may output a discrete signal to the device switch, so as to enable the device system. Accordingly, it is possible to reduce the power consumption of the apparatus during a standby mode, so as to improve a utilization efficiency of power supply.
