System Overview

Softswitch128® is a switching system that is ideal for small to medium sized switching projects. A system consists of panels, control stations, occupancy sensors, and photocells. Softswitch128® panels contain Lutron’s one million cycle Softswitch® relay and the Softswitch128® Controller.

Softswitch128® is easy to install and simple to program. Softswitch128® also includes a CEC/Title24 approved astronomical time clock for system automation.
