Patent ID: 7515023

Claim:
A micro-switching device comprising: a base substrate; a movable portion including an anchor part and an extending part, the anchor part being connected to the base substrate, the extending part extending from the anchor part and facing the base substrate, the extending part comprises a body having an electrode carrying surface on a side opposite to the base substrate; a stationary member connected to the base substrate; a movable contact conductor provided on the electrode carrying surface of the extending part; a first stationary contact electrode connected to the stationary member and including a first contacting part facing the movable contact conductor; a second stationary contact electrode connected to the stationary member and including a second contacting part facing the movable contact conductor; and a first driving electrode formed separately from the body on the electrode carrying surface of the extending part on the same electrode carrying surface of the extending part as the movable contact conductor; wherein the stationary member includes a stationary surrounding part and a plurality of stationary island parts each of which is connected to the base substrate and corresponds to a respective one of the first and second stationary contact electrodes, the stationary island parts being spaced away from one another, spaced away from the stationary surrounding part, and spaced away from the movable portion via slits extending along the stationary island parts and the movable portion.
