Abstract (en)
[origin: US4375055A] 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.
