marine boat toilet

I used to use RS components

RS PRO Vertical Stainless Steel Float Switch, Float, 300mm Cable, NO/NC, 250V ac Max, 200V dc Max | RS

The add states the following

Warning​

The cable entry point must NOT under any circumstances be submerged. The mounting thread and cable entry must be above the highest level of the liquid.
I just dont understand what it means! are they saying you can unscrew the mounting thread and draw in some of the cable?

The depth of the switch can be changed with an extension tube fitted to the screw

SSF67B25B75 | Sensata / Cynergy3 SSF67 Series Vertical Stainless Steel Float Switch, Float, 1m Cable, NO/NC, 250V ac Max, 120V dc Max | RS

But that one states the following

Two Independent Switching Points
Lower Float Make on Fall, and Upper Float Make on Rise
Meaning that the on off position is allready set. Or are you saying the tube extends? as I do see it stated in listing

46906612 | WIKA RLS3000 Series Vertical Stainless Steel Float Switch, Float | RS

But dose it telescope?

Lots more here

Vertical Float Switches | RS

They dont acrually state that they are for wast tank usage. As our friend above stated that a lot of float switches are not suibable for waste

They sell just about everything for marine toilets.

But for 300 quid i decided to forget about them and later that idea of buying one off of the shelf

 

[tinny tim]

Just Google "lift station float switch." Very common, can't foul, easy to replace.

So is this the same as this one

If you wish you can have any number and positioned at various heights

https://za.rs-online.com/web/p/float-switches/3488021

You can set this type to various heights as many as you wish

They bough have some device in the middle. is that device for mounting to the tank and if so can the wire go up and down it bough ways?

 

[tinny tim]

Same as the one in post #91

I have to say that without "the bring a bracker" they do look very simular

Sorry, yes they can foul, in more ways than one! Seriously having worked with sewage systems on ships with all sorts of indicators and sensors. I can categorically state that if it is in the tank it will foul, at some point. That applies to all types of sensor, even the so called solid state capacitive types. You can only start to imagine what a bit of wet bog roll can get up to when let loose! Not to mention the stuff that can "Grow" on them

But do you use the blue chemical?

Having looked at all of the ideas on what kind of float switch to use, i think the 2 in the photos above now would be best!
But they are just images, with no links to any web site selling them.

Dose anyone know the name of them, what type of float switches they are called. So i can look them up in the UK where I live to find a suitable seller?

Thanks

ok so it states its a "MECHANICAL SWITCHING FLOAT SWITCH"
#But a google search for that brings up something completly different

By shining a torch through self coloured polyethylene it is perfectly possible to see the contents. Photo here Toilets, holding tanks and associated matters

NO. They don't look the same and work on a different principle.

I see a lot of DIY on this toilet; but I dont see any waste tanks to it

Suggest you look a bit more thoroughly. There are two waste tanks, one a wrap-around type, the other a custom HMWPE tank made by Tek-tanks. One of the photos in the latter group shows me shining a torch on the top surface, revealing the contents.

yes i see it now! but i though it was an inlet tank and not a waste due to its location
