Most likely a ba9s led bulb holder which has a spring loaded center pin with a separate bulb. The bulb should indicate the voltage on the side, some that I use are 240VAC/DC. Normally you would connect the two solder lugs to L1 and L2 power after the switch. I would be concerned with that holder design if you wire it to 240VAC and have any exposed metal contacts that you could touch. Better off to get a LED holder were the wires/spades go into the body of the switch and the locking screws are recessed to prevent any touch contact. Something like this:
