The Siemens 3SB5000-4HA01 is a 3-position key switch from the Siemens 3SB5 series, designed for industrial control panels, machine-control systems and automation applications. It features a 22 mm round plastic construction, I-O-II three-position configuration, maintained operation, key removable in the right position, 2 × 50° operating angle and holder.
Its key-operated design is suitable for applications where machine operating modes or control functions need to be selected and maintained with controlled operator access.
The 3SB5000-4HA01 provides three defined operating positions:
I → O → II
The central O position can be used as an OFF or neutral state, while positions I and II can be assigned to different machine functions.
Typical configurations include:
The actual function of each position depends on the connected electrical control circuit.
The 3SB5000-4HA01 is maintained, meaning the selected position remains mechanically held until the key is turned to another position.
This makes it suitable for applications where the selected operating mode must remain active.
Typical uses include:
The 3SB5000-4HA01 allows the key to be removed in the right position.
This can be useful when the key position is part of an operator authorization or access-control procedure. After selecting the required position, the authorized operator can remove the key according to the machine's control arrangement.
Potential applications include:
The exact safety or authorization function depends on the complete control-system design.
The switch has a 2 × 50° operating angle, providing two 50° movements around the central position.
The operating sequence is:
I ← 50° → O ← 50° → II
This provides clearly defined mechanical positions for selecting different machine operating states.
The 3SB5000-4HA01 features a 22 mm round plastic construction, making it suitable for standard industrial operator panels and control cabinets.
It can be installed alongside compatible Siemens 3SB5 components such as:
The product specification includes a holder, allowing the key switch to be installed as part of a compatible Siemens 3SB5 operator interface.
This makes it suitable for OEM control panels, automation cabinets and industrial machine-control stations.
