Siemens 3SB3500-4LD01 22mm CES Key-Operated Switch
Siemens 3SB3500-4LD01: 22mm metal CES key-operated switch.
The Siemens 3SB3500-4LD01 is a 22mm metal round actuator for key-operated switches, featuring a CES key lock. It provides latching operation across two switch positions (O-I) and includes two keys. The key can be removed in the 'O' (Off) position. This model is phased out, with the SIRIUS ACT 3SU1 series being the successor, and the preferred successor type is 3SU1050-5BF01-0AA0 + 3SU1550-0AA10-0AA0.
This type of key-operated switch is commonly used for secure control of machinery and electrical circuits, ensuring that only authorized personnel can change the operational state. Applications include industrial control panels, access control systems, and safety interlocks where positive latching is required. Industries served are manufacturing, automation, and utilities.
