Abstract:
A micromechanical acceleration switch comprising:an electrode element comprising at least one rod;a proof mass;a housing; anda spring element connecting the electrode element and the proof mass to the housing, wherein the electrode element is mechanically connected adjacent to the proof mass, and wherein the spring element connects the electrode element and the proof mass with the housing so the electrode element and the proof mass can pivot, in use, about an axis, wherein:the at least one rod includes a contact point and is flexible so as to provide a resilient contact between the contact point on the at least one rod and at least one contact area located on the housing at a predetermined pivot angle of the electrode element;the at least one rod has a mass considerably smaller than the proof mass; andthe proof mass has a centre of gravity located at a given distance from the axis through the spring element.
