Pressure switch

[bigegg]

The pressure switch(? I think that's what it is called) on my compressor doesn't work properly.
It's a nupower 90l 2hp?
The switch cuts out the motor when it reaches full pressure, but the manual "off" switch doesn't work, so I have to wait for the tank to fill before I pull the plug.

I want to fix it, is this the right thing?

It looks like the correct part.
Do I just connect the mains cable, and the air supply to it?

I also need a new dial for the regulator.- it reads, and adjusts, but the glass is broken.
Can that just be replaced like a weldgas dial?

If you remove the black plastic cap usually there is a adjuster in there, this will change where the compressor kick's in and cuts out too.

The cap is loose/smashed, and the push "off" button is missing.
It's not really a big deal - I've been using it as-is for the last 6 years, but for the sake of a tenner, Im hoping to fix it.

Looking at that ad it looks like you will get new gauges with it !

Is that what those are?(!)
Wonder why they're shown face down...
Probably marked in Hanzi.
