Title: SWITCH CONTROL SYSTEM
Abstract:
The invention relates to a switch control system for controlling a switching device, by means of which a current path (1) is opened or closed. The switch control system according to the invention comprises a controller (4) for controlling settings of the switching device and an acquisition device for acquiring information relevant to the control of the switching device. The acquisition device is formed with an aperture (9) or filter (18), and a light path leads from the controller (4) to the aperture (9) or to the filter (18) and from there back to the controller (4). The acquisition device is equipped for a movement of the aperture (9) or the filter (18) for influencing the light path in accordance with the information relevant to the control of the switching device. The switch control system according to the invention leads to a reduction in the influence of electromagnetic interference on the switch control and therefore creates a precondition for the use of electronic switch controllers.
