The SPS System combines the look and feel of membrane systems, yet it is composed of individual removable and replaceable modules.  The system is built around a socket/bezel into which the modules plug.  The modules can be grouped and arranged into the desired configuration.  The SPS switch module Repair Parts Kit, available through AI, offers the individual components needed to repair the modules in the field.  This kit saves time and cuts repair costs which benefits both the repair center and the aircraft owner.
