Hello,
Excited to design, using relays, corresponding switches and timers, a control diagram that has a function as follows:
When user presses the push-button, a lamp turns on and remains that way (self-latched). After a small time delay when the user re-presses the same push-button the light goes off and so on repeatedly...
Regularly in control diagrams, there are several logic laws that user must obey in order to have an efficient system functioning. In this case, a single input CANNOT create different outputs.[1]
I know that there are self-latching relays, and one can program a chip to make a counter and do this small function, but the intention is to exercise drawing industrial control montages.
Before posting problems related to [1], I have used a single push button with an N.O switch and another N.O auxiliary one that both function under the same order of button switch. The circuit is as follow and is 100% functioning:
I've labeled the push buttons as 1 referring to two N.O switched for the same P.B
The purpose of creating this thread, is to hear comments, and opinions whether if the above circuit is achievable using a single N.O switch from the push button instead of two, without disregarding law referred as [1].
I have such circuits but all of them failed, due to the fact that the same N.O switch even if interfaced to timers, cannot make more than one decision that is passing current or not.
Since all were failed, no need to upload them.
Awaiting your comments.
