Abstract
The invention relates to electrically controlled switching devices in which a movable member can occupy at least two stable positions. The invention has for its object to provide a switching device in which the movable member is a dielectric body having received a persistent electric charge. This body can occupy stable positions defined on an insulating support by conductive pads. The switching is produced by a potential difference applied between the conductive pads.
Claims14
An electrically controlled switching device comprising a frame of insulator material and at least one movable member;
- said movable member having in relation with said frame at least two rest positions;
- said movable member comprising a dielectric body carrying a permanent electric charge;
- said frame being provided with at least two distinct electrically conductive pads for causing said movable member to be retained by electrostatic influence, in any one of said rest positions;
- electric bias means being connected to the said conductive pads for causing said movable member to switch across the gap separating said conductive pads.
