Abstract

Electronic broken thread indicator is for textile machinery or similar. Contacts closed in the event of a breakage complete a lever voltage circuit using a semi-conductor; so illuminating a warning lamp. A more complicated form uses a semi-conductor circuit to lock in the electrical supply, either single or three-phase, to the machinery. Closing the contacts activates one semi-conductor, illuminating a warning lamp and at the same time breaking the circuit ensuring the supply, so stopping the machinery. In both instances the circuits use low voltage obtained by transformer from the main supply.
