ABSTRACT:
A centrifugal switch for preventing overspeed of a rotary shaft driven by an electrical motor is arranged to open the electrical circuit to the starting windings at a predetermined speed of rotation. A split slip ring arrangement is engaged by metallic conducting elements urged into the conductive position by a compression means, which, when the compressive force is overcome, allows the contacts to move outward from the slip ring, to break the electrical contact. The critical rotational speed can be readily adjusted by changing the weight of the metallic conducting elements or by changing the tensile force of the compression spring.
