Control circuit for electric setting motor - has positioning component movable forwards and backwards between two end positions with end switches in motor feed conduit applied mechanically to opening contacts

摘要

End switches (2,3) in each of the motor feed conduits (4,5) are provided, of which one is mechanically moved onto an opening contact (6,7) when an end position is reached. A first conduit (8,9) leading from the opening contacts (6,7) connects the opening contact of the end switch (2,3) of the one feed conduit (4,5) with a connecting point (10,11) between the motor (1) and end switch of the other feed conduit (4,5). A second conduit (12,13) leading from the opening contacts (6,7) connects the opening contact of the end switch to a connecting point (14,15) of the same feed conduit (4,5) upstream from the end switch (2,3) and has a permeable diode (16,17) for the current flow from the opening contact (6,7) to the connecting point (14,15). USE/ADVANTAGE - Aiding closure of motor vehicle doors. Reduced number of connecting leads.
