Abstract
Switch operating device (100) with: a gesture sensor operating a switch (103) with a non-tactile push-gesture performed with a heat emitting part. The gesture has an approach phase (111) during which the part approaches the sensor, a waiting phase (113) during which the part remains proximate to the sensor, and a withdrawal phase (112) during which the part is moved away from the sensor. The sensor detects heat emitted by the part with at least one pixel and outputs per pixel a signal (51 to 54) with signal deflections (56, 57) corresponding to a temporal intensity curve of heat detected by the pixel while the gesture (115) is performed. A signal processing unit (101) which determines performance of the gesture from a temporal succession of signal deflections. An actuator (104) is controlled by the signal processing unit and operates the switch when the gesture is performed.
