The disclosure provides a flexible pressure switch. A flexible electrode region and a flexible non-electrode region are formed on a flexible printed circuit board at the bottom layer of the flexible pressure switch, two flexible electrodes separated from each other are arranged in the flexible electrode region, a conductive elastic composite body is adhered to and located on the flexible non-electrode region through an elastic adhesion layer, a pressure contact cavity region directly facing the flexible electrode region is formed on the conductive elastic composite body, and an upper surface of the inner wall of the pressure contact cavity region can contact the two flexible electrodes simultaneously or successively so as to switch on the circuit when being pressed. The flexible pressure switch is simple in fabrication process, low in cost, stable in performance and suitable for mass production.
