Derale16730 Single Stage Fan Controller

Why they make it with the"tiny,fragile"threaded peg on it is just a bad idea,you cant screw it tight or it just snaps off and it being that small screwed into a larger brass adapter i believe the adapter dissipates the heat more than the tiny peg absorbs,used the same type for elec cooling fans and temp would be 20° higher before what the temp switch is stated at,i insulated mine with a peel and stick insulating tape like i use in hvac to insulate txv valves so it would actually hold heat for it to register,has to be a better design,let me know if youve found one

Wanted name brand reliable switch for backup generator system. Did not realize it was full current rated. Should last forever in the relay based system or allow that to be bypassed if relay fails.

What I received was an switch with 1/8" threads on the base and the adapters. What is pictured is what I wanted, a switch switch with 1/8 NPT threads. There is a huge difference in the two. The part # on the packaging matches this listing. So the pictures used for this item are clearly misleading, especially if someone is wanting something very specific. I am disappointed with what I received. I would not have spent my money on this if accurate pictures would have been used.

The description says that the switch closes at 180 and opens back up at 165. The switch I received didn’t close until 200 then it opened back up at 180. I was expecting the fan to come on at 180 and turn off at 165. I’m about 20 degrees off despite the description of the part.

Look at the pictures closely this is what you will actually get, It is not what is pictured in the description.

Works great for my 59 Corsair! Thank you.
