NONCONFORMITY DETECTOR FOR ELECTRICAL EQUIPMENT

PURPOSE:To detect not only the disconnection of a magnetic coil but also the nonconformity of a plunger previously by mounting an engaging section to the plunger and driving a latch engaged with the engaging section by another auxiliary magnetic coil. CONSTITUTION:When an operation command is given, an engaging section 24 for a first plunger 22 is engaged with nowhere, the first plunger 22 is moved at all strokes, and a trigger device 23 is operated. When voltage is applied to a checking terminal for a magnetic coil 21, on the other hand, the first plunger 22 is worked, but a latch 28 and the engaging section 24 are interlinked, and the trigger device 23 is not driven. However, a first limit switch 25 is operated, and the magnetic coil 21 is moved normally including the first plunger 22. When voltage is applied to a checking terminal for an auxiliary magnetic coil 26, a second plunger 27 is worked, and a limit switch 30 is operated through a limit-switch driving piece 29, thus determining the normal operation of the auxiliary magnetic coil 26 and the latch 28.
