SCHALTANORDNUNG DES ELEKTRISCHEN KREISES EINES GARNBRUCHFUEHLERS FUER TEXTILMASCHINEN, INSBESONDERE FUER SPINDELLOSE FEINSPINNMASCHINEN

A magnetically responsive circuit is arranged in the yarn breakage detection portion of a knitting machine for providing a visual indication of yarn breakage and for simultaneously switching the operating state of a drive coil-actuated clutch which feeds yarn into the machine. The drive coil is serially connected with a magnetically actuated reed switch which responds to the detection of yarn breakage to switch the operating state of the drive coil. A normally disabled lamp or other illumination device is connected to the drive coil and to the switch by means of a diode. The diode is poled to maintain the lamp disabled while the switch remains unoperated, and to energize the lamp when the switch is operated in response to a detection of yarn breakage.
