Abstract

Means for detecting defective latch needle condition in a knitting machine wherein an electrically non-conductive feeler is mounted in the path of movement of the needles so as to be deflected by any latches in defective condition. The feeler is insulatingly carried by a coil having a core mounted therewithin and insulated therefrom. The core and coil define a normally open electrical switch which is closed when the feeler is deflected by a defective latch needle. A control network is provided and is responsive to the closing of the switch for interrupting the energization of the drive means for the knitting machine. The control network provides sufficient power for lighting as many detector lamps as are activated at one time, while still providing the requisite power for interrupting the energization of the knitting machine drive means.
