    Need a time delay circuit for my float switch and 12v pump?

    i cant see two relays on that scematic as i said to you before the above blew the switch

    Need a time delay circuit for my float switch and 12v pump?

    I don’t belive we ever had a duel relay circuit The only other chematic I tried welded the switch together I think ericman’s circuit has done the job But I have used 2 cigereeete lighters to create a load and I managed to get the load to about 5 amps and the switch has not blown so I’ve...

    I was hoping 13amps I suppose your going to tell me it dose not work like that

    Need a time delay circuit for my float switch and 12v pump?

    I have set up and tested the above schematic Using a domestic car charger as the power source The sequence has work and it has not blown the float switch but I could only get the chargers to show a maximum of 2 amps and I wanted to put a heaver load through it just to test it properly relay...

    Need a time delay circuit for my float switch and 12v pump?

    Ericman I have looked at your diagram again and swapped the switches round in the diagram The sequence now works If you are so sure that the current wont blow the switches then I think I will make a circuit up on my desk But before I do I need to know what some of the items are in the...

    quote="Spark123";p="1140108"][ No, the current cannot flow in the direction you have indicated on the diagram as the diode prevents this. If you missed the diode out of the wiring then yes, you could overload the switch. As I have said on a number of occasions now, you need to fit the diodes...

    Need a time delay circuit for my float switch and 12v pump?

    NO! How can you have ‘water on its way up’ if the pump/light is switched off This is a ‘pump in pump’ not a ‘pump out pump’ you know What’s the K in the diagram and what are the U1 and U2

    Need a time delay circuit for my float switch and 12v pump?

    The only things I can think of now why the original manufactured schematic dose not work Is there is some thing missing from it Ever the original float switches wear designed for a heavy load, and to date I have not been able to find any that will hold such a load Or it’s the tank fill...

    Need a time delay circuit for my float switch and 12v pump?

    Well when you found it I’ll have one The turbulence of water /bouncing of the float is not rely a problem It the amount of water in the mixer tank that can be consume to the amount of water it can supply is nearly even That’s why we have a rapid on off effect

    Need a time delay circuit for my float switch and 12v pump?

    I have been down to the machine today and re-wired it up as above I had thoughts in the back of my mind about the above and it came true!!! The lower float switch has some how split (the one I substitute from the low water engine stop) showing a no circuit all the time no matter what...

    Need a time delay circuit for my float switch and 12v pump?

    spark123 I've re drawn your schematic Im worried about the load from the pump on to port 87 and there being a positive from live on to port 30 and then onto the float switches Surly one of them is going to be overloaded Just wondered why you drew your diagram so the switches wear the other...
