Abstract
A reversing contactor apparatus in a single case is disclosed, comprising electro-mechanical locking means. These means which comprise a mobile mechanical locking piece, further having surfaces for actuating locking switches, are placed substantially in the plane of a median dividing wall, on each side of which each of the two contactors of the apparatus are disposed; these conductors connect these switches in series to each contactor coil and, respectively, to a connection terminal.
