Means are provided for generating oscillations in the looped conductor, as well as means for detecting a variation in the oscillating conditions induced by a change of state of the electrical circuit due to the closure of one switch and indicating that the sensor has met up with a yarn. Due to the detection of the variations in the oscillating conditions, it is possible to find out the number of breakages occurring in the textile machine.
