Patent ID: 7382218

Claim:
Micromechanical switch, comprising a deformable bridge, attached via its ends to a substrate, and actuating means to deform the deformable bridge so as to make an electrical contact between a first conducting element securedly affixed to the substrate and arranged between the bridge and the substrate, and a third conducting element arranged on the substrate at the periphery of the bridge, switch wherein the deformable bridge comprises at least a first insulating layer wherein a hole is drilled, in which hole a conducting material is arranged salient from the bottom face of the bridge so as to form a second conducting element designed to come into contact with the first conducting element when deformation of the bridge takes place, a conducting line connecting the second conducting element to the third conducting element being arranged on the first insulating layer, wherein two ground planes are arranged on the substrate on each side of the bridge and connected to the second conducting element, the conducting line connecting the second conducting element to the two ground planes.
