I don’t know about your part number but if you have an LED light, a battery and a resistor to match the led color and battery voltage there’s an easy answer to whether it’s latching or momentary.
Left side is spst momentary soft switch, as advertised it is soft and makes a slight squeak as it passes through the bushing but there’s not much question it doesn’t latch. Right side is a 3pdt latching switch and there is both an audible click and a feel of the tumbler or literally “latch” flipping from side to side, the sensory feedback is prominent.
There are indeed momentary switches which will give a bit of a firmer throw, but I’d just hook one pole to the battery and put a resistor in line with an LED and see if clicking the switch proves to turn on the LED light or just lights it and it dims as you release the actuator.
If you were sent the wrong switch no reason to keep it, as it won’t do you any good unless you intend to build a few guitar pedals. Let us know the result.
Here’s a resistor calculator, you also need to know the forward voltage of your LED but otherwise it’s pretty simple. When in doubt, use a resistance greater than what’s necessary.

I can dig up a link to these parts if you’d like but the supplier is in the US so I don’t know that it’s of any use to you. From my experience, since the switch is not microphonic in the sense of how it works electronically it won’t matter how noisy the click is in a recording, but if you’re performing ambient guitar looping in front of a crowd and you CLICK to loop, it detracts a bit from the mood.
