1. A wireless switch detection system for a vehicle comprising:
- a central transmitter for transmitting a transmitter signal;
a remote vehicle switch for mounting in a vehicle at a location spaced apart from said central transmitter, said remote switch having at least two states indicative of a vehicle condition; and
a tag circuit separated from said central transmitter, said tag circuit being responsive to and powered by said transmitter signal, said tag circuit detecting the state of said remote vehicle switch and, in response to said transmitter signal, transmitting a tag signal according to the state of said remote vehicle switch.

Abstract
A wireless switch detection system (10, 100) includes central transmitter (22, 109) for transmitting a transmitter signal. The system (10, 110) also includes a remote switch (28, 128) spaced apart from the central transmitter (22, 109) and having at least two states. A tag circuit (32, 136) is responsive to and powered by the transmitter signal. The tag circuit (32, 136) detects the state of the remote switch (28, 128) and, in response to the transmitter signal, provides a tag signal indicative of the state of the switch (28, 128). A central receiver (26, 111) receives the tag signal.
