A TWIST-GRIP CONTROL DEVICE, IN PARTICULAR FOR MOTOR VEHICLES

摘要

A twist-grip control device that produces a pair of electrical signals indicative of the relative angular position of the rotor portion. These signals are correlated with one another such that one of the signals may be used as a control signal indicative of the extent of an associated controlled physical magnitude desired by the user, and the other signal may be used as a control signal adapted to enable the detection of the occurrence of operating malfunctions or failures when these signals are no longer correlated with one another in the predetermined relationship.
