Abstract

A manual contactor-inverter for hoists, characterized by the fact of constituting a central plate of insulating material which is mounted with symmetry on their opposite sides: at its longitudinal center, a fixed and grooved framework at the lower end of which the side walls are widened symmetrically configuring in them a notch of appropriately curved profile in which the central part of a rotating rod plays which at its ends has respective cylindrical contactors mounted, which rod is supported by an oscillating piece about an axis supported by the frame being configured in its lower-back part a transverse groove whose walls act as stops between which the end of another oscillating piece plays around an axis also supported by the frame, located next to the upper end thereof, to which oscillating part a push-button is fixed, concurring in addition the circumstance of coming holds the oscillating piece that takes the button to the action of a spring whose tension has a permanent tendency for its free end to rest against the outer wall-stop of the groove of the other oscillating piece, forcing it to rest against ears at stop functions provided, projecting laterally, at the lower end of the frame and also acting on the oscillating part carrying the cylindrical contactors, a coil spring which by traction forces the rapidity of the disconnection; On the other hand, near the sides of the frame and with symmetry with respect to this, are mounted on each face of the central plate, two sets of clamp-type contactors in which to establish mutual contact by closing the circuit, the contactors can be introduced cylindrical when pressing the button on the corresponding side.
