An optical matrix switch station (

1

) is shown mounting a plurality of optical switch units (

15, 17

), each of which includes a mirror (

29

), moveable in two axes, for purpose of switching optical beams from one optical fiber to another. A mirror assembly (

41

) includes a single body of silicon comprising a frame portion (

43

), gimbals (

45

), mirror portion (

47

), and related hinges (

55

). Magnets (

53, 54

) and air coils (

89

) are utilized to position the central mirror surface (

29

) to a selected orientation. The moveable mirror and associated magnets along with control LED's (

71

) are hermetically packaged in a header (

81

) and mounted with the air coils on mounting bracket (

85

) to form a micromirror assembly package (

99

) mounted in each optical switch unit.
