1.   And it may someday lead to the creation of a new breed of computers based on tiny electronic switches, each no thicker than a single molecule.

2.   As optical cables evolve to handle more and more wavelengths, which is crucial in expanding capacity, electronic switches must be reconfigured or replaced.

3.   Assemblers of its electronic switches no longer need to score at a sixth-grade level on a math test.

4.   A D.J. flipped electronic switches next to a refrigerator.

5.   By bouncing the lightwaves off MEMS mirrors instead of running them through electronic switches, networks could improve Internet efficiency.

6.   Currently, when a fiber optic cable carrying dozens of different wavelengths of light reaches an electronic switch, each wavelength must take a different path through the switch.

7.   To activate a function, such as recording, the user looks for about two seconds at a particular spot that serves as an electronic switch.

8.   Very early on, people found that machines, first using brass gears and then electronic switches, could calculate.
