Dallas Center IA 515-720-2463 | Bobby is confussed.
Normally Open and Normally Closed.
Is? On the Deere switch in the photo below,
With the planter lowered, and the button on the switch is not against the plate. The switch is on [electric currect passing thru switch]
With the planter raised, the button on the switch is depressed. The switch is off [ no currect thru the switch]
I am thinking that is Normally Open.
Right or wrong?
Also a Electric Solenoid Hydraulic Valve,
No currect to the valve, means no hydraulic flow.
With currect to the valve, there is hydraulic flow.
Is that Normally Closed.
In other words:
Does Normally Open mean - If nothing is happing to make the deal work, as button pushed, wisker pushed, or electric currect, the switch is OFF.
In the picture the planter is raised and the switch is off.
