Abstract
The invention relates to a device for articulating a moving blade pivoting on its base. The mobile member is constituted by a blade fixed to a float, which floats on a liquid contained in a cavity made in a base, the liquid being kept in the cavity by capillarity. The nature and dimensions of the float are adapted to the liquid density. The cavity dimensions are large enough to permit the float to move, without mechanical jamming. The mobile assembly, blade and float is prevented from escaping from the cavity by at least one bridge welded to the base towards the ends of the float. Application to switches with blades wetted by an electricity-conducting liquid.
Claims11
A device for the articulation of a moving blade, whose plane pivots in an angular manner on its base, wherein the moving blade is fixed to a float floating on a liquid contained in a cavity in which it is held by capillarity and which is made in the base, the nature of the float material and its dimensions being such that the hydrostatic buoyancy which is exerted by the liquid is equal to or exceeds the weight of the mobile assembly constituted by the float, the moving blade and the liquid film wetting the said blade, the equilibrium of the force ensuring that the articulation operates independently of its position in space.
