<p>PROBLEM TO BE SOLVED: To provide a sensor switch by which a ratio of a response difference in the detection distance is automatically set to a prescribed value. SOLUTION: The switch is provided with a sensor signal reception means that provides an output of a sensor signal corresponding to a distance up to an object. A distance revision means 3 changes a level of the signal by the signal reception means 1 and a distance recognition means 4 recognizes the distance. A hysteresis of a signal with respect to the rate of change is stored so that a ratio of a response difference in the detection distance is a prescribed value or a prescribed function and the hysteresis is set in response to the recognized distance. Thus, the ratio of the response difference in the detection distance is made to the prescribed value or the prescribed function.</p> |
