Abstract: An optical fiber switch assembly is disclosed. The assembly includes a housing which contains an optical fiber switch which is switched by rotating at least one member between first and second switch positions. An actuator is provided for rotating the member between the switch positions. The actuator includes a shaft connected to the switched member and a fixed magnet carried on the shaft. Electromagnetic elements are disposed on opposite sides of the fixed magnet. The electromagnets are energized to alternate a magnetic field and urge the fixed magnet to rotate and move the shaft in alternate rotational directions. A stop mechanism is provided to ensure accurate rotational positioning of the shaft.

Abstract: An optical fiber switch assembly is disclosed. The assembly includes a housing (62) which contains an optical fiber switch (80) which is switched by rotating at least one member between first and second switch positions. An actuator (76) is provided for rotating the member between the switch positions. The actuator (76) includes a shaft (82) connected to the switched member and a fixed magnet carried on the shaft. Electromagnetic elements (102,103) are disposed on opposite sides of the fixed magnet. The electromagnets (102,103) are energized to alternate a magnetic field and urge the fixed magnet to rotate and move the shaft (82) in alternate rotational directions. A stop mechanism is provided to ensure accurate rotational positioning of the shaft.
