Siemens 3SB3500-4BD01 22mm RONIS Momentary Key Switch

The Siemens 3SB3500-4BD01 is a 22mm round metal actuator equipped with a RONIS lock for key-operated switches. It offers momentary contact action across two switch positions (O-I), requiring the key to be held in position for the contact to remain active. It includes two keys and supports key removal in the 'O' position. This model is also compatible with RONIS key switches SB31, 455, and 421. This product is phased out, with SIRIUS ACT 3SU1 series, specifically 3SU1050-4BC01-0AA0 + 3SU1550-0AA10-0AA0, being the preferred successor.

Momentary key switches like the 3SB3500-4BD01 are used for temporary activation of functions, such as emergency stops, system resets, or specific test modes where continuous engagement is not required. They enhance safety by ensuring a function is only active while the key is deliberately held. Applications are found in industrial machinery, control systems, and emergency management.
