Proximity switch (10) having a first sensor element (S1) with a first sensing region (16) for sensing an object moving through the first sensing region (16), a second sensor element (S2) with a second sensing region (18) for sensing an object moving through the second sensing region (18), and a third sensor element (S3) with a third sensing region (20) for sensing an object moving through the third sensing region (20), wherein the sensing regions (16, 18, 20) of the three sensor elements (S1, S2, S3) are arranged in a spatially distributed manner such that an object moving in a particular direction through the sensing regions enters the sensing regions (16, 18, 20) in succession and leaves the latter again in the same order, wherein there is an overlapping region (22) in which the sensing regions (16, 18, 20) overlap such that an object situated there is sensed by all three sensor elements (S1, S2, S3), and wherein provision is made of an evaluation logic unit (24) having a state machine (40) for detecting the direction of movement and for identifying a defective sensor element.
