Product description

The Siemens 3SU1000-4BF11-0AA0 is a 22mm round key-operated switch constructed from durable plastic. It features the RONIS lock mechanism (key number SB30) and includes two keys. This latching switch offers two positions (O-I) with a 90° actuating angle (10:30h/13:30h). A key feature is the ability to remove the key in both the 'O' and 'I' positions, providing flexible operational control and security.

This key switch is suitable for applications requiring maintained operational states and flexible key management. It can be used for controlling machinery, access points, or any system where a key is needed to maintain a specific operational state, with the added convenience of key removal in either position.
