Title: pressure switch
Post by: bbdave on February 05, 2016, 12:18:37 pm

I need a pressure switch to stop the fill of a water ballast bag so a NC switch that opens with pressure, any suggestions where to get one?

Norbert Bruggen sells them.

Thunder Tiger Neptune used them too, if you can find someone that sells spares.

Thanks I can't see any on norberts site, I bought a Neptune dive bits and bobs but couldn't get it to work plus I think the pressure switch is N.O. So works the wrong way for me.

It's here. Not sure what the switch configuration is. Ask Norbert.

An alternative is have a go at making your own or just have a microswitch positioned to trigger when the bag is full.

Don't be afraid of Norbert, his English is quite good and he's always happy to help out

I'll have a go with a microswitch but need a reliable mount I've been through a few saline bags in testing  {:-{

If you use a microswitch, put the bag inside a cuff e.g. plastic pipe with some holes drilled in it.

This should restrict the volume of the bag helping to prevent bursts, and will make it easier to position a microswitch.
