A control circuit for detecting a loop state includes a signal indication module, a three-way switch, a remote control module, and a detection module. The three-way switch and the remote control module are connected in series between the load and a power source. When the three-way switch is pressed down or the remote control module receives a wireless signal sent from the signal indication module, the remote control module or the three-way switch is switched to form a closed/open circuit state between the power source and the load. The detection module connects the load and the remote control module, and detects an actuation state of the remote control module and the load when receiving the wireless signal, so as to generate determination information and state information, and display the information, such that a user can know whether the load loop runs normally.
