Hi Friends

I was trying to convert a 12V pulse signal to a 12 V toggle signal,

i would have done it in minutes using 52 but furtunatly i can't use it

So i decided to use relays,

After trying a lot i came here... for some hints


What I wanted to do:-

Breif -- With one pulse comming in, i wanted to latch the pulse say switch ON an LED and with the next pulse comming in i wanted to unlatch the signal say off the led

Detail Example --- Imagine that a toggle push button is connected to a LED in one side and to +vcc on the other, ofcource the gnd of LED is connected to supply gnd. now if the button is pressed the led switches ON and if the button is released then the LED switches off, I want the led to switch ON and stay on with one press and release of the button and with the next press and release of the button the LED shall switch off... Mind it i can use only relays here.


I was able to latch the pulse signal but was not able to cut it with a next incomming pulse, this means that i was able to keep the led ON with the first Press and release of the button but was not able to switch it off with the next press and release..

Still trying to put logics on ON and NC.... hope some one can give me some hints..
