Pressure switch went out on an little 2hp Campbell Hausfeld air compressor and they friggin want $60 for the part.
What little I use this one I suppose I could leave it wired direct bypassing the switch as I have it now but don’t relish the idea of having to eyeball the thing to shut it off manually when using it.
I’d buy something new instead but wonder if there is a cheaper way to get the critter working than $60 on a little plastic box.
Thanks.

Northern Tool has them for about $35.
Second Northern Tool. The way you are using it now is extremely dangerous.
Ya, MrT was trying to teach me how to run an extention cord up on the roof so I could plug and unplug the thing by listening to the laboring sound it makes when getting up around 100 or so.Behind the ostensible government sits enthroned an invisible government owing no allegiance and acknowledging no responsibility to the people.

Your boss was? I think you need to find a new boss.
Find a new boss and call OSHA when the compressor is on the job. Be sure to take a picture first too.
I dunno. MrT pays cash and at $8 an hour I can't quibble. 100 ft ext cord costs only what?Behind the ostensible government sits enthroned an invisible government owing no allegiance and acknowledging no responsibility to the people. [Theodore Roosevelt]
$8/hr.? How much does McDonalds pay? You would probably be money ahead if you worked at McDonalds. Do not need a car or tools to flip burgers.
Was being a bit facetious with my comments here.
Am serious about the pressure switch in that it just went out today and will be ordering a replacement.

rez,
local auto parts store (NAPA) stocks them as cheap as I found them mail order.
They can't get your Goat if you don't tell them where it is hidden.
I'll check that out. Thanks.

My CH compressor has a pop off valve that would keep it from blowing up but you are wasting electricity. Compressors tend to lose efficiency as the pressure increases and I doubt they will ever go much over the design pressure anyway. If you hook your clamp on ammeter on there you will see the highest current draw is around 100 PSI and as it starts getting up around the 150 PSI shutoff the current drops off quite a bit.
When I read Arcflash's response (112281.4) I thought the same thing. Theoretically it shouldn't be dangerous to run without a pressure switch because all compressors should have a pressure relief but it would likely burn out the motor by placing under too high of load. I suppose there is a slight chance that the pressure relief is faulty, stuck, or improperly sized, thereby creating a dangerous situation.So, I'm not advocating running a compressor without a pressure switch but if you really gotta use it and don't have the part yet...gk
The other point I was making is the load on the motor actually decreases when the pressure starts getting up near the design limit of the compressor since it is not moving as much air. You can prove this with a clamp on ammeter. It is similar to why a vacuum cleaner motor speeds up when the hose is clogged.
A pressure switch us a pressure switch. I wouldn't operate it without one. You'll get busy and forget.

Ya, that's what I told 'em.
He said don't worry about it and just unplug it ever so often.

I worked with a guy like that. His shortcut was to carry fewer sizes of nails. He'd carry long ones and just cut them short when he needed to.

rez,
I use Surplus Supply for lots of parts. New adjustable switch for $15,

Years ago I bought one from Grainger.
Take a look at http://www.grainger.com/Grainger/wwg/productIndex.shtml?operator=retrieveProdLevel1Index&prodLevelList=Compressor%257CCompressors%252C&prod_level_selected=Compressor
then select pressure switches. It lists 166 of them to pick from.
