Thermoswitches

[olionel]

Hi;

I need to control the radiator fan on a current project, and was going to use the ecu's water temperature sensor (which can be made to read at one of the unused pins) via a transistor and a relay, or just a relay, but came across something called a thermoswitch, which makes my life bugger loads easier. Do these things come in preset ranges? Or can I configure one myself. Who sells em, I couldnt find that many on the net. Does anyone know a supplier in UK?
(Note: The ecu im using is a pile of crap and is 8 years old so ye.. gay)

here are all types, like the one built into the side of your radiator. thats preset, at around 100'C
and then there are variable ones like what you get in a hot water cylinder, you just turn the dial and set your temp like that.
you can also get ones with leads and a sensor that you rest against the head, or under the spark plug.
there is lots of options.

As hmmmnzy says...

You can buy one from any OEM of most bikes.
Not dead cheap but affordable and you really want something that will work every day (for years & years).

It will have the temp. range stamped/engraved/magic markered on the switch and are either normally closed, normally open or both.

You decide how you wish to set it up.
Most probably through a relay circuit as the fan will pull a substantial current which yo do not want the switch to feel.
But you know that already.

I would have thought that these thermo switches were neigh on fool proof, but mine seems to have stopped working. I cant get any reading across it at all, even when i boiled it in a saucepan.
