Class Information
Number: 335/17
Name: Electricity: magnetically operated switches, magnets, and electromagnets > Electromagnetically actuated switches > Automatic circuit-interrupting devices (e.g., circuit-protective devices) > With switch condition signalling, indicating or alarm means
Description: Subject matter wherein the circuit interrupting device includes signalling, indicating or alarm structure whereby the condition of the switch, whether open or closed, physically inoperative, etc., is automatically communicated to an operator or other interested observer by visual or audible means. In order to be classifiable in this subclass the signalling or indicating means must include structure in addition to an operating lever or other operating means whose position is dependent upon whether the contacts are open or closed.
