Apparatus for a micro-electro-mechanical switch that provides single pole,
double throw switching action. The switch has two input lines and two
output lines. The switch has a seesaw cantilever arm with contacts at
each end that electrically connect the input lines with the output lines.
The cantilever arm is latched into position by frictional forces between
structures on the cantilever arm and structures on the substrate in which
the cantilever arm is disposed. The state of the switch is changed by
applying an electrostatic force at one end of the cantilever arm to
overcome the mechanical force holding the other end of the cantilever arm
in place.
