動作表示装置。A relay drive display circuit formed of a relay drive signal source, a battery power supply, a relay circuit in which a current is passed in response to a signal from the relay drive signal source to drive the relay, and a display element and a switching transistor. and when a current flows through the relay circuit, a switching transistor of the relay drive display circuit is turned on to cause the display element to emit light;
The relay comprises a self-holding circuit which, when the relay circuit is turned off, causes a self-holding current to flow from the battery power source to keep the switching transistor of the relay drive display circuit on and to continue displaying the light emitting element. Operation display device.
