Abstract: In connection with an automatic control device for the cleaning power of a vacuum cleaner, comprising a blower, a blower drive motor and an associated control circuit for the latter, it is proposed to provide two vacuum switches adjusted to different vacuum threshold value or one vacuum double switch presetting the two vacuum threshold values, and to drive a storage (counter, capacitor), whose output configurations determine the manner in which a phase control circuit, which is connected in series with the blower drive motor, is driven, by a corresponding configuration of the switching conditions of the said switches. It is possible in this manner, with only two existing vacuum switches, to operate the blower drive motor at a predetermined power plateau, without any switching actions, so long as the vacuum generated remains within a predetermined window.

Abstract: A circuit interrupter manually opens and closes its contacts by use of a manually rotatable handle which acts through a collapsible linkage rotatably connected to a crank extension of the handle and rotatably connected to a rotatably movable contact support. The rotatable contact support is urged away from closed contact position by a main spring and in moving from one contact position to the other the axis of the rotatable connection between the handle crank passes over a center line defined by the center of rotation of the handle and the rotatable connection between the linkage and the movable contact support providing a toggle action to hold the movable contact in selected open or closed position. Upon overload, the mechanism causes collapse of the collapsible linkage allowing the movable contact support to move and open the contacts.

Abstract: An apparatus is disclosed for providing an electrostatically actuated mechanical switch utilizing a cantilever beam element fabricated by solid-state microfabrication techniques. The apparatus reduces the required pull down voltage and lowers the switch inductance by separating the pull down electrode and contact pad. The pull down electrode is placed further away from the fulcrum of the cantilever beam then the contact pad to optimize the mechanical advantages which allow for a reduced pull down voltage. The contact pad is placed closer to the cantilever fulcrum to reduce the associated switch inductance. The gap between the contact pad and the cantilever beam is less then the gap between the pull down electrode and the cantilever beam to insure that the cantilever makes first contact with the contact pad.
