OK here is a video demo to try and best explain what it is I am trying to do here.
OK video is up, you might have to check my last postYes, i think your getting us confused here,
Do you want to trigger the timer when the rocker is pressed, and again when the rocker is released?
Simple answer is "No" As in left also NEEDs a pulse, All three switch states need a pulse.Ok, rocker switch to the right, pulse timer, rocker switch in centre pulse timer, rocker switch to the left no pulse, yes or no?
Try this in the 'BU' mode.But do you know if there is a way for the latching switches to also generate a pulse through the timer when they are switched off?
Or is that so complicated it would not be worth the time?
Before you connecting the LED to the pin 3 , you should test that two R and two LEDs independently to make sure they won't light up when the power is upper than 9V, if they light up then you better in series with a diode for each LED and recalculate the values of R.View attachment 94289
I wonder if something like this will work? I found this circuit on Google that has an indicator state for output state High and Low. My thought was that perhaps the two states could be sent to our other "Timed" 555 circuit via the trigger input of this circuit from the rocker switches.??
This is the image I found online:
Thanks macf, but I would need this explained in a lot more detail in order for me to understand what it is and how it works, and how I would implement it into my scenario.Try this in the 'BU' mode.
I did test out this circuit on it's own just wired to a 9V battery, I used a couple of 470R resistors for the two "R" resistors and the circuit works.Before you connecting the LED to the pin 3 , you should test that two R and two LEDs independently to make sure they won't light up when the power is upper than 9V, if they light up then you better in series with a diode for each LED and recalculate the values of R.
Please don't forget to cut and compress to as 800x600, I already did this for you, next time don't forget again, thanks.Ok mike, try this circuit, extra diodes, resistors, and a transistor.

With the switch in either left or right position you get your pulse from the capacitors as normal, when the switch is in the off state ( centre) the two diodes Da and DB wont conduct and the transistor will turn on via Rc and Dc, and will give a pulse to the555 timer.
Thanks Dodgy dave, this one looks doable only I'm unclear on a few things in your diagram, I redrew it a little more clearly with some "?" marks.Ok mike, try this circuit, extra diodes, resistors, and a transistor.

I'll try making a much clearer one in photoshop just to make sure I have it correct, but this looks very promising dodglydaveNo you have missed out Rc, and its pin 1 that goes to negative supply not pin 4, look at my drawing.
Awesome Dodgydave, Take a look at this and see if it looks OK, if it all looks good then I can test this out and post a video with the results.The circuit is correct upto pin 2 of the 555 timer,
then you need to have your timing resistor and capacitor on pins 6,7 as normal, supply pins 4,8 to positive, pin1 to negative, output on pin 3.
Why you need that bjt stage for?Awesome Dodgydave, Take a look at this and see if it looks OK, if it all looks good then I can test this out and post a video with the results.
I think my timing 1M was lower i'll have to look at what I have on the breadboard
