Abstract:
A micro-machine switch which causes a contact electrode to make contact with or separate away from a signal line formed on a substrate, to thereby turn on or off said signal line, comprising:(a) first to N-th lower electrodes formed on said substrate, wherein N is an integer equal to or greater than 2; (b) first to N-th upper electrodes supported on an insulating means facing said first to N-th lower electrodes, respectively; and (c) means for vertically raising and lowering said first to N-th upper electrodes between a first position where said contact electrode makes contact with said signal line when electrostatic force is generated between said first to N-th upper electrodes and said first to N-th lower electrodes, respectively, and a second position where said contact electrode is separated away from said signal line when said electrostatic force is not generated; wherein said insulating means is isolated from said substrate.
