Abstract

PURPOSE:To make the range of detection broad, by providing the rotary ball supporting the horn at the back of the horn, providing the ball receiving surface in the housing, bearing the rotary ball with this ball receiving surface to enable to turn the horn. CONSTITUTION:In the ultrasonic switch transmitting and receiving the ultrasonic wave through the provision of a microphone 3 to the horn 1, since the horn 1 is borne with the rotary ball 4 via the rubber cap 5, the horn 1 can be turned in the range of a constant angle theta in all directions. Further, since the rotary ball 4 is pressed on the ball receiving surface 9 of the housing 8 with the retaining spring 6 via the retaining rubber 7, the horn 1 can be borne with a constant holding force.
