Abstract (en)
[origin: EP0392761A2] An operation display apparatus for an electromagnetic relay, wherein the division voltage corresponding to the impedance ratio between the primary coil and the secondary coil is applied upon the operation display circuit so as to effect the display operation, and when the primary coil is disconnected, the operation display circuit does not operate, because the current does not flow even into the secondary coil, and the brightness of the light emitting element of the operation display circuit changes, because the voltage to be applied upon the operation display circuit changes.
