This class includes the control of those various power-transmission means, motors, and brakes the motions of which occur at the completion of a cycle of operations or which are due to contact with the material handled by the machine or to the defective action of the parts of the machine operated or to such operations as arise from the initiation of measures for the safety of the operator.
