An infrared transmitter tube and an infrared receiver tube are arranged on the side of each button and positionally correspond to a display lamp arranged in the button. A circuit control device for controlling the infrared transmitter tubes and the infrared receiver tubes is disposed in the button box. The infrared transmitter tubes and the infrared receiver tubes are connected with the circuit control device. The buttons are 2-3cm in spacing. The infrared sensor elevator button set is simple and reasonable in structure. A rider can successfully push the elevator buttons to take the elevator by infrared sensing with no need of touching the elevator buttons, so that transmission of bacteria and viruses is effectively prevented and public safety is guaranteed. The buttons are spaced, so that mistaken pushing can be effectively prevented and utilization efficiency of the elevator is improved.
