Whale Microswitches

Recommended Posts

Our van uses the problematic pressure switch system currently, and I wish to convert it to the micro switched system that our old van had.

 

Main reason being that as our van is fully off grid and running on solar the voltage does fluctuate and interferes with the pressure switch, and I simply prefer the micro switch arrangement.

 

My problem is that I do not wish to pay upwards of £5 per a switch when I am going to require 6 of them.

 

I can not imagine that there is anything specific about the switches except their size.

 

My question is has anyone ever measured a genuine whale one ?, or has someone else managed to source the correct size one but not from whale ?.

 

I have access to RS and Farnell but if someone could give me the dimensions of the switch it would make my search much easier.

 

Thanks in advance

Whale now do a controller which you can retro fit. This does away with need to keep adjusting pressure switch. It's called the IC. Costs around £35 but you might need to replace pump.

Details on their web site.

Thanks for that, However this would entail as you say a new pump and new water inlet fitting.

 

I think I would prefer to just go to micro switches, less to go wrong (Hopefully)

Hi,

Needed some years ago to replace a micro in a tap . I removed it and took it to a radio shop who matched it up. On reasembling the tap i rewired the tap(s) to switch the power on/off to a relay thus removing the heavy currant from the tap micro ( micro now switched 25 m. a. instead of 4/5 amps ) we never had to replace another micro. The relay handled the heavy load caused by the motor ( relay designed to handle 30 amps ) .

Hi David.

 

This is exactly what I intend doing, especially considering that I have to run new cables to all switches it will be beneficial to use the relay as it will mean I can get away with lighter cable (Cheaper) :)

Mike - I replaced the m/switches on my last van and got a spare at that time. I looked at it and thought, like you, that RS or Farnell would have one for less than a quid. But I left it in the 'van when we sold it on!

Simply replace the pressure switch with a normal switch. ...switch on when needed & off when finished!

That's what I am currently doing, but SHMBO says it should all be automatic, have explained that if she turns the switch on then the water will come from the taps automatically, but No that's not good enough for her :(

Hi Mike & deb,-

Just looked at Maplins cat and found the following ,- N95AQ and they have a number of other micro's -- with sizes so you should have no problem. If the required switch has a roller/ lever they can be removed. When i did my "modification" i "slugged" the relay coil with a small capacitor ( electrolytic ) this caused the relay to stay closed for a second or two after the tap was closed thus giving a bit more pressure in the pipes--- stopped the water pump " hunting ".

david.

 

P. S. - Have a look at Maplins web site for info.

Thanks David for your advice.

 

Unfortunately without one to measure I think I am going to have to bite the bullet and buy just the one genuine one,, then can measure it etc and find a duplicate.
