Hi Guyz

i am looking for the simplest push button Circuit like the one used in water pumpers ..

Push once to "trun on" push again to "Turn off"

USING FLIP-FLOPS

some one told me that i could Use Daul D FF

Biraaa

 

Connect /Q back to D. Then use the switch to pulse the clock. Realistically, there needs to be more, but that is the topology.

 

A pushbutton switch with a maintained contact (not momentary) can do the same thing without the flip-flop.

 

Moved to new thread in the Project Forum

I ran across this thread and thought I'd hijack it as it's so old but is very relevant to what i'm doing.
Using a simple Dual D FF as indicated, using a Schmitt trigger with the "momentary on" pushbutton w/debouncing; I want to drive 2 sections of a 4066 quad bilateral switch for the switching of line level signals. Tho /Q is tacked to D. Can /Q be tapped also to a switch actuator of the 4066? Or would it be better using Master/Slave configuration? The purpose is to switch from one active signal path to another (A/B switch). This will be multiplied into a digital signal switching matrix for my guitar rig. Is there a particular Dual D FF IC that would be recommended? Will the Schmitt give sufficient "edge" to toggle? I would prefer to have leading edge vs trailing for timing reasons.

It's been a long time away from design work, so forgive my ignorance or "thickness".

Thx!

 

I need the exact same idea for this design I'm doing. I'm anxious to see what's the best way.
