Automatic 12V Switch Wiring

This Project started out to replace the auto switch for my Bilge Pump in the boat. The previous owner had the float switch wired up with "speaker" wire - which did not instill confidence in me for his wiring skills - and possibly why the pump did not work.




I bought a new switch (and even read the instructions). From that I made the following drawing as a WIP guide ..... (nice paper ;-) )

I first wired everything up using the old switch and the thing worked :-) Testing the Float Valve a few times I found it only worked some of the time. Back to the shop and swapped the new switch for a new float switch. Wired it all up again - perfect.

Now where am I going to save this drawing for future reference - VOILA ! here.

This then got me thinking "What has this got to do with this Forum"? Think outside the square .... How about a security device for your camper or caravan while your away?

You could replace the Float Switch with a pressure plate in the annex doorway. The Bilge Pump could simply be a light (or a bloody big air horn at head height - just remember to turn it off when you get back).

The mind boggles ......
