Siemens 3SU1000-4BM01-0AA0

The Siemens 3SU1000-4BM01-0AA0 is a key-operated switch designed for industrial control applications. This 22 mm round switch features a durable plastic housing and includes two keys for secure operation. It offers three distinct switch positions—marked I, O, and a momentary contact—allowing for flexible control options. The switch actuates with a precise 2x45-degree turning angle, positioned at 10:30, 12, and 13:30 hours. Additionally, the key can only be removed in the 'O' position, ensuring safe and intentional locking. This reliable component is available through BSP Automation, providing a practical solution for systems requiring secure, keyed switching functions.
