@pyper The pins should be labelled C (Common), NO (normally open, centre pin) and NC (normally closed). You should have continuity between NC and C when switch is not depressed, and continuity between NO and C when not depressed. There is no continuity between NO and NC. If you don't have continuity between NC and C, then possibly it's just a really cheap switch packaged as a microswitch!
It's usually not too much of a problem having the microswitches wired NO, but the voltage is floating, so any interference (eg from high voltage such as heater wires or stepper motor wires) can possibly trigger the endstop. This doesn't happen when wired NC.
Here's mine, wire NC, pin labels just about visible:

Ahh, I see you wired up directly to the switch.
I was probing through the 3-wire jack. I guess they didn't even run traces for NC.
Will check on that.
