Abstract

PURPOSE:To make a multifunctional indication easy to see without increasing power consumption by the change-over indication of desired function according to a touch switch operation of touch hour and the like. CONSTITUTION:When a switch SW1 is momentarily touched to turn ''on'', the outputs Q5 and Q1 of a JK-type FF5, 1 become high-level synchronizig with the clock and the output Q2 of a D-type FF2 remains high-level by an ''and'' gate 13 continuing high-level through a ''nand'' gate. Similarly the output Q3 of a RS-type FE3 becomes low-level to generate the indication change-over signals S1-S3 which is a combination of required levels. Said state is reset by the control pulse being put out after a lapse of 2sec from the terminal O2 completely closing the switch SW1 by the counting circuit 6 of which reset is released by an FF1 or an or gate 10. Similarly, while the SW1 is kept switched ''on'' more than one second, the signals S1-S3 vary according to the touching time and touching operation of repeated switching ''on'' within one second, only the corresponding indication is indicated easily to see with no dividing the indication face and with no increase in power consumption.
