Abstract

PURPOSE: To provide a level display unit which can intuitively grasp the level with simplified circuit and less power consumption by a normally closed display unit and one display unit becoming on state in response to the level of a control signal.
CONSTITUTION: Binary control signal is applied from control terminals 1, 2 and 3 to a level control circuit 4 to control the signal level and to decode it by a decoder 7 to make all display units 16W22 OFF or either one unit ON. A display unit 23 is always on state to confirm the signal level by one of the display units 23 and 16W 22. Thus, it can simplify the circuit without losing the level confirming function.
