Product Description

Siemens 3SB5000-4AA01 Key Switch – 22 mm, 2 Positions O-I, Maintained

The Siemens 3SB5000-4AA01 is a 22 mm round plastic key switch from the Siemens 3SB5 series, designed for industrial control panels, machine-control systems and automation applications. It features 2 positions O-I, maintained operation, key removable in the left position, a 100° operating angle and holder.

Its key-operated design provides controlled operation for machine functions where the selected state needs to remain mechanically maintained.

2-Position O-I Key Switch

The 3SB5000-4AA01 provides two defined operating positions:

O → I

These positions can be assigned according to the application's electrical control philosophy.

Typical functions include:

• OFF / ON
• Disable / Enable
• Stop / Run
• Control permission
• Machine function selection
• Equipment activation
• Service operation
• User-defined two-state control

The actual function of each position depends on the connected control circuit.

Maintained Operation

The 3SB5000-4AA01 is maintained, meaning the selected position remains mechanically held until the key is moved to the other position.

This makes it suitable for applications where the selected machine state needs to remain active.

Typical applications include:

• Machine ON/OFF selection
• Enable/disable control
• Operating-mode selection
• Service-mode control
• Equipment control
• Function selection
• Operator authorization

Key Removable in Left Position

An important feature of the 3SB5000-4AA01 is that the key can be removed in the left position.

This can be useful where the key position forms part of an operator authorization or machine-access procedure.

Potential applications include:

• Authorized machine operation
• Maintenance access
• Service control
• Restricted machine functions
• Equipment authorization
• Operator access control

The actual safety or authorization function depends on how the key switch is incorporated into the complete control system.

100° Operating Angle

The switch has a 100° operating angle between its two positions.

The operating sequence can be represented as:

O → 100° → I

This provides a defined mechanical movement between the two maintained operating states.

22 mm Round Plastic Construction

The 3SB5000-4AA01 features a 22 mm round plastic design, making it suitable for industrial operator panels and electrical control cabinets.

It can be installed alongside compatible Siemens 3SB5 devices such as:

• Pushbuttons
• Illuminated pushbuttons
• Selector switches
• Indicator lights
• Emergency-stop devices
• Other control and signalling components

Holder Included

The product is specified with holder, supporting installation in compatible Siemens 3SB5 operator-panel assemblies.

This makes it suitable for OEM machinery, automation cabinets and industrial operator stations.
