How to correctly wire an on/off toggle

[Dadbeh]

i am using this illuminated toggle for my on/off switch on an amp but i cant figure out how to wire it.

it has 3 legs marked one, two, three. and and the data sheet has this:

i am taking the hot wire from the fuse and connecting it to pole #3.
and i am taking the hot wire from 1 and connect it to the transformer of my power supply but it doesnt seem to be working. there is something i am missing.

I think:
1/ Hot wire from fuse to 3
2/ Output to transformer 2
3/ Connect 1 to zero volt line to put on the neon. Unless the indicator is aLED in which case you correct resistor and diode to limit the current.

#3 is not a pole, it is a tag. It is a single-pole switch.

I strongly recommend that you make and use a lamp limiter when testing newly built mains powered circuits.

1/ is to the indicator so goes to neutral.
2/ is output from switch
3/ is live input.
When switch is off indicator is off.
When switch is on indicator is one too.
1 isn't a pole just neutral connection for indicator.

^^^^^^ what Nigel said.

For sake of completeness: the other end of Power Transformer primary winding also goes to neutral, so when toggle switch is ON, both Power Transformer and Neon indicator are ON at the same time..

And use heatshrink on ALL of them so that no mains wiring is exposed.
