PROBLEM TO BE SOLVED: To provide a mat radio switch system, which enables a centralized control of the detection by a plurality of mat radio switches. SOLUTION: Only one unit of receiver 3 is arranged almost in the center of a facility, and mat radio switches 2, 2, 2 and 2 are placed outside each entrance, respectively. When a switch is pressed down upon applying of a pressure from the above on the mat radio switch 2 by an aged person and the like, the mat radio switch 2 transmits its ID and a detected signal to the receiver 3, which transmits an acknowledgement signal carrying the information of the detected signal reception to the mat radio switch 2, and displays the pressed-down state of the switch on a display device connected to the receiver 3. Thus, an administrator can control four mat radio switches 2, 2, 2, 2 in a centralized manner by grasping the state displayed on the display device, and constitute the mat radio switch system 1 at a low cost.
