A device for inputting an elevator calling command and an elevator control system including the device. A device for inputting an elevator calling includes one or more button units, each of the button units including a switching element and a variable resistance circuit coupled with the switching element. The variable resistance circuit includes a button switch and a display element coupled in parallel, and a resistance value of the variable resistance circuit varies with a state of the button switch. The device further includes a control unit configured to determine a state of a corresponding button switch based on the resistance value of the variable resistance circuit within each of the button units, and to apply a pulse width modulation signal having different duty cycles onto a control terminal of a corresponding switching element based on the state as determined.
