Micro-switching device actuated by low voltage

摘要

A micro-switching device actuated by a low voltage is provided. The micro-switching device includes a spring operating elastically; a membrane formed on one side of the spring, being held by the spring; and a lower electrode formed below the membrane, for generating an electrostatic attraction when a voltage is applied thereto, wherein the membrane is non-planar. This micro-switching device is advantageous in that it can be actuated by a low voltage and prevents the adhesion that occurs commonly in micro devices.
