Electronic – Unable to configure a simple IEC connector with an illuminated switch

connector

I have this IEC connector with an illuminated single-pole switch.

Here is how it looks like from back side:
enter image description here

As you see above the earth, line and the neutral are mentioned. But for the switch side there is no marks so I marked them as A B and C.

Here is the catalog for this type of connectors:

If you go to page 277 you find this model named as C20 IEC Inlet.

I cannot see any kind of information how line and neutral will be wired to the illuminated switch. Is there a standard or how can I figure this out?

Edit:

Let's say I would know which pin is 1 2 and 3.

There can be two ways to wire this:

Config 1

or

Config 2

enter image description here

Dashed gray line is when the switch is OFF. I think the pin 2 is the fixed pin.

But which configuration is better than the other one?

Btw I only tried Config 1 and the switch makes arc like sound when one turns it on.

Take a look a page 2 of that document and you’ll see this: enter image description here This says to me that you want to connect the hot input to pin 1, your load to pin 2 and neutral to pin 3 to complete the circuit for the light.

Now as for which pins are 1, 2 and 3, that’s not clear but take and ohmmeter and check to see which pins open and close with the switch: those are 1 and 2. If the light stays on even with the switch open, you have 1 and 2 switched - easy to fix.
