Frequently asked questions

What does the 'O' inscription signify on the Siemens 3SU1050-0AB20-0AD0 pushbutton?

The 'O' inscription on the Siemens 3SU1050-0AB20-0AD0 pushbutton typically signifies 'Off' or 'Stop'. As a momentary contact device, pressing the button activates a circuit, and releasing it deactivates the circuit, making it suitable for functions that require a temporary action.
