Abstract
A bimorph switch electrically connecting a traveling contact and a fixed contact. The switch comprises a substrate having a front face, a rear face, and a through hole penetrating from the front face to the rear face; a fixed contact extending from an edge portion of the aperture of the through hole towards the inside of the aperture; and a bimorph section holding the traveling contact at a position facing the aperture and driving the traveling contact. One end of the bimorph section may be formed on a silicon oxide layer formed on a front face of the substrate.
