Product description

The Siemens 3SU1000-4BC01-0AA0 is a 22mm round key-operated switch featuring a durable plastic construction. It utilizes the RONIS lock mechanism with lock number SB30, comes with two keys, and offers two switch positions: O (OFF) and I (ON). This momentary contact type switch has an actuating angle of 45° (10:30h/12h), with the key removable only in the O position.

This key switch is designed for applications requiring controlled access or operational control, preventing unauthorized operation. It's suitable for machine tools, access control systems, and general industrial equipment where a key is needed to activate or deactivate functions. The momentary action ensures the circuit is only active while the key is in the 'I' position and the switch is held.
