Abstract
A switch detection device using RFID tags is disclosed. The switch detection device includes a RFID tag, a conducting circuit loop and a switch connected to the conducting circuit loop to form a control circuit. The switch is controlled to turn on or off, leading to the closing or opening of the control circuit. The RFID tag detects the state of the conducting circuit loop and transmits a signal representing the opened/closed state to a RFID reader. The switch detection device is incorporated to a turning operation mechanism which includes a lever lock assembly, a deadbolt lock assembly, a window sash lock assembly, an odometer wheel, a hinge provided with a first hinge member and a second hinge member interconnected by a central axle, a door closer, a water faucet, a rotatable switch, or a rotatable lock.
