ABSTRACT:
A control handle for electro-mechanical devices, such as the brakes of a train or other vehicle, is disclosed. The control handle incorporates elements for electrical switching as well as elements for measuring the angle of rotation between the control handle's rotating portion and its stationary portion. Some of the switching elements and measuring elements are combined onto a single printed circuit board in order to reduce size, complexity, and cost.
