1. A multi-wavelength switch comprising:
- (a) an input channel producing an input electromagnetic signal (a) at least one rotatable reflector element for receiving and switching said input electromagnetic signal;
(b) said reflecting element positioned in the space between sheets;
(b) at least one sheet being transparent;
(c) means to individually rotate said reflector within said sheets for selectably redirecting the input signal; and
(d) said reflector substantially reflecting at least a portion of the input signal to an output channel.

Abstract
This invention deals with a novel general concept for a multi-wavelength switching ensemble which is controlled electrically, electromagetically, or magnetically. A switching system is presented that achieves electrical isolation between the input and output channels, and yet permits the input to control the output. It allows a full 180 degree rotation of the beam which greatly exceeds the rotational capability of conventional systems. Furthermore, the instant invention permits less costly and greater ease of manufacture while providing independent amplitude and frequency modulation between the input and output channels.
