The present disclosure describes an isolator/switching assembly for use in a message terminal system. The assembly permits a pair of electronic data processors, one on-line and the other a back-up unit, each processing confidential or so called 'red' data, to interface with each other and both units to interface with and control a common peripheral device or I/O port. At the same time, the assembly provides physical and electrical isolation between the processor and the peripheral device and insures the TEMPEST security of the entire system.
