Patent ID: 6875936

Claim:
A micro-machine switch electrically connecting a first signal line formed on a substrate to a second signal line or electrically disconnecting said first signal line from said second signal line, said second signal line being formed on said substrate and having an end spaced away from an end of said first signal line by a certain gap, said micro-machine switch comprising: a supporter formed on said substrate and having a predetermined height relative to a surface of said substrate; a flexible beam projecting from said supporter in parallel with a surface of said substrate, and having a distal end facing said gap; a contact electrode formed on a surface of said beam facing said substrate such that said contact electrode faces said gap; a lower electrode formed on said substrate in facing relation with a part of said beam; an intermediate electrode formed on said beam in facing relation with said lower electrode; and an electrical insulator between said beam and said intermediate electrode and extending so as to face said gap.
