ABSTRACT:
An annunciator for a solenoid includes a conductive probe which projects into the pathway of the solenoid core piece. Upon actuation of the core piece, the probe is engaged by the core piece to partially complete an electrical circuit to an external signalling device. The probe includes a lost motion contact to insure proper making and breaking of a circuit upon further movement of the core piece into engagement with the field piece.
