A switch operating device () configured to operate a switch () with four possible types (to) of non-tactile translational gestures performed with a heat emitting part (). A gesture sensor () is adapted to detect heat emitted by the part while performing one of the translational gesture types. Four pixels (to) are arranged next to each other and output a signal (to) per pixel, wherein the signal has a signal deflection () corresponding to the temporal intensity curve of the heat detected by the thin film of the corresponding pixel. A signal processing unit () determines the performance of the translational gesture types from the temporal succession of the signal deflections (). An actuator () is controlled by the signal processing unit and operates the switch when one of the translational gesture types is determined.

Switch operating device () with: a gesture sensor operating a switch () with a non-tactile push-gesture performed with a heat emitting part. The gesture has an approach phase () during which the part approaches the sensor, a waiting phase () during which the part remains proximate to the sensor, and a withdrawal phase () 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 (to) with signal deflections () corresponding to a temporal intensity curve of heat detected by the pixel while the gesture () is performed. A signal processing unit () which determines performance of the gesture from a temporal succession of signal deflections. An actuator () is controlled by the signal processing unit and operates the switch when the gesture is performed.

Switch operating device () with: a presence sensor operating a switch () in response to presence of a heat emitting part. The presence has an approach phase () during which the part approaches the presence sensor, a remaining phase during which the part remains proximate to the sensor, and a withdrawal phase () 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 a signal (to) with signal deflections () corresponding to a temporal intensity curve of heat detected by the pixel. A signal processing unit () determines the approach and withdrawal phases from the temporal succession and the shape of the signal deflections. An actuator () is controlled by the signal processing unit and operates the switch when the approach phase, the remaining phase and/or the withdrawal phase is determined.
