Frequently asked questions

What does 'momentary contact' mean for the Siemens 3SU1050-4BC01-0AA0 key-operated switch?

Momentary contact means the switch is only active while the key is turned to the 'I' position and the circuit is closed. When the key is released, it returns to the 'O' position, and the circuit opens. This ensures the control action is only active when intentionally applied.
