The proposed floor of a jukebox for dances contains a platform with buttons, which the dancers press according to the music rhythm, detectors of button pressing, and elements for illuminating the buttons. The number and the arrangement of the buttons at the platform can be varied. As the detector ofbutton pressing, a contactless detector based on the Hall effect is used. The sensing element of the detector is coupled with the corresponding button by a spring-loaded rod.
