little drawing from their catalog page , not even identifying the 4 terminal connections, but they sure wanted you to know the hole sizes .
If you are wanting use of the switch for AC power switching of both legs . . .seems like the unit would blow up the resistor and LED on power up. the way they show the innards of the unit in their mini GREEN box illustration.
Now . . . Its possible internal interpretation in the large GREEN box.
If this were to be used for ~ 12VDC switching all would be fine, put 12VDC in to 1 and 3 would be the negative teminal.
Press the pushbutton and gold BUSS bar A moves down to short out from terminals 3 to 4.
Simultaneously the mechanically linking to gold BUSS bar B moves down to short out from terminals 1 to 2.
This lets 12VDC power flow through the switch and the LED also lights up.
YOUR SITUATION:
WITH the AC power switching situation , on power up FULL AC is then being applied across the series resistor and LED.
I could only see that situation, with the use of a NE-2 NEON lamp and high voltage dropping resistor, being used instead of the LED and its droppig resistor.
However, a LED circuit variant would be the use of a series diode to only get the positive AC nodes passing and a high 6K / 120 VAC . . . . .12K 240 VAC dropping resistor and a zener a bit higher than the junction voltage of the LED as a safety voltage snubber.
NOW, to see what you REALLY have there, take a 9 VDC battery and have an unwired switch and press the button to mechanically latch the switch on.
Then you connect battery positive to pin 1 or 2 and and the battery negative to pin 3 or 4 and see if you then have a lit LED.
Then, press to release the mechanically latched switch and confirm that the LED goes off.
Now if you were to switch ONLY one leg of the AC line down at 1 and 2 , a connected supply battery powering the LED through the top switch section alone , with battery positive to 2 and battery negative to 4 would power up the led, BUT have some AC line connectivity of that battery power circuitry , when AC power is switched on.
