It works
It works as advertised, but adjustment pressure setting is ballpark.

Great compact switch
I installed on a vacuum table and it was perfect for the box size and worked very well, also very easy to set. Great product.

what is the wiring for these used in nc operation
Thank you for your question.
The unit can be wired ether normally open or closed.
The n/c is used mostly for decrease in pressure.
Hope this was helpful
