ABSTRACT:
An apparatus for converting the rotational speed of a shaft, particularly of the driving shaft of a log propeller shaft into a proportional impulse frequency is provided with a rotary permanent magnet, means to couple it with the shaft, and at least one magnetically actuated switch positioned within the effective range of the permanent magnet, these electrical elements being arranged in a liquidproof housing of an improved construction simultaneously contributing to an optimum space saving arrangement of all parts involved.
