Abstract
To unvisualize the mechanical indicating instrument for an automotive vehicle when the ignition switch is turned off, the pointer is covered by a pointer cover below zero indication when the meter is deactivated, or a semitransparent front cover is disposed in front of the dial. In this case, the meter is offset by an offset magnet from a zero position to under the pointer cover when deactivated. On the other hand, to visualize the same instrument, when the ignition switch is turned on, lamps disposed in front and/or back of the dial are illuminated and a colored transparent pointer is illuminated by another or the same lamp in linkage with the ignition switch.
