The Siemens 3SB5000-4AC01 is a 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, 2 positions O-I, maintained operation, key removable in the right position, 100° operating angle and holder.
Its key-operated design makes it suitable for applications where a machine function needs to remain in a selected state while also providing controlled operator access.
The 3SB5000-4AC01 provides two defined operating positions:
O → I
These positions can be assigned according to the machine's control philosophy.
Typical applications include:
The exact function of each position depends on the electrical control circuit.
The 3SB5000-4AC01 is maintained, meaning the selected position remains mechanically held until the operator moves the key to the other position.
This makes it suitable for applications where a machine function or operating mode needs to remain selected.
Typical uses include:
The key can be removed in the right-hand position.
This feature can be useful where key removal is part of an operator authorization or machine-access procedure. Depending on the control-system design, the operator can select the required position and remove the key.
Potential applications include:
The actual safety or authorization function depends on the complete machine-control system.
The switch has a 100° operating angle between its two positions.
The operating sequence can be represented as:
O → 100° → I
This provides a clear mechanical transition between the two maintained operating states.
The 3SB5000-4AC01 features a 22 mm round plastic construction, making it suitable for industrial operator panels and control cabinets.
It can be installed alongside compatible Siemens 3SB5 devices such as:
The product is specified with holder, supporting installation in compatible Siemens 3SB5 operator-panel assemblies.
This makes the key switch suitable for OEM machinery, automation cabinets and industrial control stations.
