Abstract

A device for measuring the switching force at rail switches includes a measuring pin to be inserted in a joint of the switch drive. On the free end of the measuring pin a head is provided, in which an electromechanical sensor is arranged.
The measuring pin has annular raised portions or ribs arranged at different axial distances from one another outside the central plane of the joint through which the joint axis passes and cooperating with relatively pivotable parts of the joint.
