The Siemens 3SB5000-4HB01 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, left and center positions, 2 × 50° operating angle and holder.
Its key-operated design provides controlled access to machine functions while allowing operators to select and maintain one of three defined operating positions.
The 3SB5000-4HB01 provides three operating positions:
I → O → II
The three-position configuration allows a single key switch to select between two functions with a central position.
Depending on the machine-control philosophy, these positions can be assigned to:
The actual function of each position depends on the electrical control circuit.
The 3SB5000-4HB01 is maintained, meaning the selected position remains mechanically held until the operator moves the key to another position.
This makes it suitable for applications requiring continuous selection of a machine operating mode.
Typical applications include:
A key feature of the 3SB5000-4HB01 is that the key can be removed in the right, left and center positions.
This provides additional flexibility for machine authorization and operating-mode control.
The ability to remove the key in all three positions can be useful where the position of the switch must remain fixed after the authorized operator removes the key.
Potential applications include:
The actual safety and authorization function depends on the complete control-system design.
The key switch has a 2 × 50° operating angle, providing two 50° movements around the central O position.
The operating sequence can be represented as:
I ← 50° → O ← 50° → II
This provides clearly defined mechanical positions for machine operation and mode selection.
The 3SB5000-4HB01 features a 22 mm round plastic construction, making it suitable for industrial operator panels and electrical control cabinets.
It can be integrated with other Siemens 3SB5 operator devices, including:
The product is specified with holder, allowing the key switch to be integrated into compatible Siemens 3SB5 control-panel assemblies.
This makes it suitable for OEM machine panels and industrial operator stations.
