Claim:
1. An electromagnetic switching device with several regions of connection, particularly a contactor having a plurality of command terminals and one or more auxiliary terminals wherein the contactor provides a visual distinction between the command terminals and the auxiliary terminals, the device comprising: a first region, wherein the first region includes a base that is adapted for fixing the contactor to a panel, and a housing that accessibly encloses an electromagnet, the electromagnet comprising a fixed armature and a coil; a second region, wherein the second region occupies an area located substantially above the first region and is releasably attached to a top of the first region, the second region further comprising a plurality of power terminals, each power terminal adapted to receive a power conductor, and a plurality of moveable power contacts, each moveable power contact being associated with one of the power terminals and adapted to controllably close a circuit associated with the power terminal; a third region, wherein the third region occupies an area located substantially above the second region and comprises the command terminals and the one or more auxiliary terminals, the command terminals being electrically connected to the coil and located at a first height above a bottom of the third region, and the one or more auxiliary terminals being located at a second height above the bottom of the third region, the first and second heights being different from each other, and wherein the command terminals and the auxiliary terminals are distributed across the third region in an asymmetrical manner that groups the auxiliary terminals together and leaves the command terminals standing apart from the auxiliary terminals so that the command terminals are visually distinguishable from the auxiliary terminals when viewed from a top of the third region, and wherein the command terminals and the auxiliary terminals are integrated into the construction of the third region; and a fourth region, wherein the fourth region occupies an area located substantially above the third region, the fourth region being adapted for connection of accessories.
