Abstract
A switch identification circuit is provided. The switch identification circuit includes a detecting unit, a control unit, a connection unit, a first connection terminal, and a second connection terminal. The detecting unit is coupled with the first connection terminal and the second connection terminal, and configured to detect voltages at the two connection terminals to output a detection signal. The connection unit is electrically coupled with a power-supply device configured to provide a driving voltage to the two connection terminals. The control unit is coupled with the detecting unit and the connection unit, and configured to determine whether the first connection terminal and the second connection terminal are short-circuited according to the detection signal. If the two connection terminals are short-circuited, the control unit is configured to output a connection-enabling signal to the connection unit, to make the connection unit control the power-supply device to stop supplying the driving voltage.
