Abstract

Electronic tachometer switch, characterized in that it comprises means for emitting a variable frequency main signal proportional to the instantaneous speed of the medium to be controlled; first pulse generating means, capable of generating pulses of predetermined duration; second pulse generating means capable of generating very short pulses of fixed duration, activating the negative and positive impulses of the main signal to said first and second means or said second and first ones; pulse generating means for causing the disconnection of corresponding impulses and confronting means to confront the first signal, coming from said first pulse generating means, with the second signal, coming from said second pulse generating means, and to emit two different types of output signals, according to whether the pulses of the first signal overlap in time the pulses of the second signal or that these pulses do not overlap in time.
