Abstract: The invention relates to a switch-actuating apparatus (100) having a presence sensor (1) for actuating a switch (103) by means of the presence of a heat-emitting part (115) at the presence sensor (1), wherein the presence is composed of an approach phase (31), in which the part (115) approaches the presence sensor (1), a waiting phase (44), in which the part (115) remains near the presence sensor (1), and a removal phase (41), in which the part (115) is to be moved away from the presence sensor (1), wherein the presence sensor (1) is designed to detect heat emitted by the part (115) by means of at least one pixel (21 to 24) having a thin film made of pyroelectric material and to output one signal (51 to 54) per pixel (2 to 24), said signal having signal swings (56, 57) corresponding to the intensity curve over time of the heat detected by the pixel (21 to 24), a signal-evaluating unit (101), by means of which the approach phase (31) and the removal phase (41) can be determined from the succession over time and the form of the signal swings (56, 57), and an actuator (104), which is controlled by the signal-evaluating unit (101) and actuates the switch (103) as soon as the approach phase (31), the waiting phase (44), or the removal phase (41) is determined.
