Multi-level micro-switch

Abstract

The present invention relates to a multi-level micro-switch comprising a housing and a fixed supporting cylinder disposed in the center of the housing and extending upwards along the axis of the housing, wherein a plurality of multi-level supporting cylinders are sequentially and flexibly contained in the fixed supporting cylinder. The bottom of the fixed supporting cylinder is connected to the housing and a plurality of beams is constantly arranged around the fixed supporting cylinder. A slide ring is arranged on the inner side of the housing which fits with the vacancy of the housing. An inner casing is contained in and flexibly connected to the housing, touching the slide ring at the bottom end, and a conductive ball is disposed in the vacancy above the beams. The invention may choose different thresholds of detection sensitivity for each application and be typically utilized as a movement-detection unit in an electronic surveillance system, especially an anti-theft system.
