TOUCH TYPE OPERATING BUTTON DEVICE FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To provide a detecting circuit of preventing erroneous operation of a button device when placed such unstable condition that an output of a detector repeats on/off turning when a human body comes into contact with a touch plate. SOLUTION: Even when an output of a detector is placed unstable to repeat on/off operation, when a human body comes into contact with a touch plate 1 of a touch type operating button device for an elevator, the detector output can be stabilized by a detecting circuit 7, and a high reliable touch type button device for the elevator can be provided.
