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.
