Frequently asked questions
What is the function of the normally closed (N.C.) contact in the 800T-QBH2BD1?
The normally closed (N.C.) contact in the 800T-QBH2BD1 is closed when the button is not pressed, allowing current to flow. When the button is pressed, the contact opens, interrupting the circuit. This is crucial for safety applications.
