What is the significance of the NC contact in the Siemens 3SU1150-0BB20-1CA0 pushbutton?
The 1 NC (Normally Closed) contact in the 3SU1150-0BB20-1CA0 means the circuit is normally closed and opens when the button is pressed. This is often used in safety circuits where releasing the button must break the circuit.
