In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions.
a 0-simplex is a point, a 1-simplex is a line segment, a 2-simplex is a triangle, a 3-simplex is a tetrahedron, a 4-simplex is a 5-cell.
In topology and combinatorics, it is common to “glue together” simplices to form a simplicial complex. The associated combinatorial structure is called an abstract simplicial complex, in which context the word “simplex” simply means any finite set of vertices.
I'll be wiring my new 4-switch crossover with simplex wiring for sure! Yessir!

In communications, simplex is a system that allows only one party to be heard at a time, i.e. a push-to-talk intercom or two-way radio. Duplex refers to a system where two or more parties can be heard at the same time, such as on a telephone.
That's what immediately came to my mind when I saw this, but as Frankie said it was just Tyco's attempt to market a "simpler" system of layout wiring.

umpdan31: JadeFog: i found a brand new in the box ConCor PRR mail car. Although the ones that I already have are all heavyweights with 6 wheel trucks, this one is a lightweight with 4 wheel trucks. I also picked up a few assorted couplers. Glad he was open again.

umpdan31: The mail car was 10 bucks. Not bad for a brand new car.
