MWS, Modular Wiring Systems, provide low cost installation of branch
circuit wiring for lighting and power. Using modular components
that plug together, MWS can be installed in a fraction of the time of
hardwiring. Plus, MWS offers the advantage of relocating fixtures and
outlets in future renovations.

Switch Drops can also be connected together for multiple switch
locations.
