Abstract
A wireless switching system includes a central transmitter unit which generates a plurality of electromagnetic frequencies. A plurality of switches within the electromagnetic field each selectively open and close a resonant circuit having a unique resonant frequency. When the user activated switch closes its associated resonant circuit, the resonant circuit consumes energy from the electromagnetic field at its resonant frequency. The central transmitter unit detects this energy consumption and the frequency at which the energy consumption occured and consequently activates a vehicle function associated with the closed user activated switch.
