Abstract

A manipulator or traction key for machinery, comprising a box, a cable connected to a substantially flat plate, slidable, mounted inside the box, the urea plate opening through which passes a first cam, the first being mounted cam on a rotating camshaft loaded with spring having a longitudinal axis substantially perpendicular to the plane of the plate, two microswitches mounted inside the box for application with a second light mounted on the camshaft, one of the microswitches being connected to a circuit for supplying electrical power to the machinery, the other being connected to a signaling circuit, and a manual control mounted on the camshaft outside the box, such being the arrangement that when the cable is pulled the flat plate slides so that the edges of the opening are applied to the first cam and rotate the cam shaft or when the control is rotated the second cam is rotated from a first position, in which the electric power supply microswitch allows electric power to be supplied to the machinery, a second position in which the electric power supply microswitch cuts off the electrical energy and : the machinery is disconnected, and such that when the manual control is rotated to rotate the second cam beyond the first or second positions, according to the cam it actuates to the signaling microswitch.
