Small brush type DC motors, equipped with a solenoid controlled brake, drive the switch contacts from one position to the other. The motors operate through a gear train and are electrically disconnected and locked in position upon completion of the transfer.

The entire switch is contained in a sealed inert atmosphere. Electrical power is required only during transfer, usually less than 100 milliseconds. Contacts are single or double throw with ratings to 500 amperes. Primary uses are power and signal transfer between energy sources and equipment, safing systems, interstage power and signal transfers.
