CONTROL SYSTEM FOR AN ELECTROMAGNETIC SWITCHING DEVICE AND ELECTROMAGNETIC SWITCHING DEVICE CORRESPONDING THERETO

摘要

The invention relates to an electromagnetic switching device (1). The aim of the invention is to control at least the correct connection of an input (2) and an output contact (3) by means of a contact bridge (4). To this end, a control circuit (6) is coupled to the contacts (2, 3) and an indicator for correctly connecting the contacts (2, 3) is detected by evaluating a contact potential (U) that is dropped over the contacts (2, 3) and is conveyed to the control circuit (6) when a connection order is given before the contact bridge (4) is converted into a connecting position.
