Abstract
A control circuit for an input device including a micro-switch is provided. The control circuit includes an input circuit, a receiver circuit, a control unit, and a detecting unit. The input circuit includes a first contact and a second contact for electrically connecting to the micro-switch. The receiver circuit includes a third contact and a fourth contact for electrically connecting to the micro-switch. The control unit is electrically connected to the first contact and the third contact for providing an input signal via the first contact to the micro-switch and receiving a switching signal from the micro-switch via the third contact. The detecting unit detects a voltage of the second contact to generate a detecting signal. The control unit receives the detecting signal to determine a type of the micro-switch.
