Re: [CAD_CAM_EDM_DRO] E-STOP SWITCH

A normally open contact is opened until you press or toggle it, normally
closed is the opposite.
Some switches you press or toggle to make it change then you press or toggle
it again to make it change back.
sometimes called press on press off, or toggle on and toggle back off.
I momentary contact closes when you press it and opens when you release it
or visa versa.
Hope this helps.
Jim
