Many thanks, I now understand the logic behind it. Now all I need is a parts list and wiring diagram. The pump I will be using is a 12v pump. I have a 12v power power adaptor. If its not too much trouble could tell me what parts I need and how I should wire them up. Again any help is much appreciated. Thanks
Thanks for your reply, I have Had a look at the diagram but don't understand still, how do you get the pump to stay on until both switches rise? How are they wired to give that result. This is just what I need for a project I'm doing to automate water changes. Thanks again.
@haroonshaukat The relay is wired as a latching relay. Best thing to do is to do an internet search for 'latch relay circuit'. There are many examples on the internet that will explain this. There are also YouTube videos about latching relays.
Continued from previous... Curious to know how the middle float switch does not turn the pump off when the float rises? Also I really want to make one of my own. Do you have a parts list and circuit diagrams etc. will be willing to pay you for? Thanks in advance
@haroonshaukat If the water level is at the max, there is a chance of water ripple causing a float switch to bounce which causes the pump constantly go on and off. So the two left switches work together and both need to be down in order to turn the pump on. And to turn the pump off, both switches need to be up. If you had one switch to turn the pump on & off you have that chance of water bounce. Check out this diagram which is what my design is based on.
can you elaborate on the dual low level switch setup? how does it stay on until the higher one gets lifted?? i'm wanting to setup an auto top system for my sump soon and your design looks awesome! sorry to bring up an old topic again.
This is exactly what i'm trying to do but i'm stumped!!! I know what i want it to do in my head and its exactly like this but i can't figure out t the wiring!! I'm not really worried about the leds tho i just need one to indicate it stoped working. You know where i can get help on the wiring?
@rashiidefukazumi I did plan on making this into a partial kit, but I lost some of the files on the computer it was on and need to recreate them. So right now, I do not.
@rashiidefukazumi It can be done with two float switches but you will not have the safety overflow protection. The two leftmost float switches determine the low and high water levels. Lower one activates the pump, upper one stops the pump. The right one is there as a fail safe if the upper float switch fails.
I dont understand how you wire the first two together. Unless the middle float is special. When the water level is low, the middle float will fall turning on the pump. But why does it stay on when that float is up?
Can't explain exactly how they are wired, just both connect in a latch fashion to the relay. There are examples and diagrams on RCentral. Check the DIY section.
This unit works in the sump, not the tank. It would be difficult to show it working in my sump as the float switches would be hard to see. That's why I have the video this way. The water in the background just shows when the top off pump is running.
No completed plans yet, but they are about 50% done, but it's summer and moved on to other projects. Maybe will finish the plans in the fall. I know it will be a hit. This one here has been working great since January, no flaws.

wow!im so impress of ur work...
btw if i use only 2 of the float switch one is sense the water level n the other is to sense for overflowing can tat be happen as the same as tis?

As water evaporates in the Aquarium, this controls refilling the tank.
