Siemens 3SU10004BC010AA0 RONIS Key-Operated Switch – 22 mm, SB30, O-I, Momentary

The Siemens 3SU10004BC010AA0 is a RONIS key-operated switch from the Siemens SIRIUS ACT 3SU1 series, designed for controlled operator functions in industrial control panels, machine operator stations, automation systems and electrical cabinets. It features a 22 mm round plastic design, RONIS lock number SB30, 2 supplied keys, and 2 switch positions O-I.

Unlike a latching key switch, this model uses a momentary contact type, making it suitable for applications where a temporary key-operated command is required. The switch has a 45° actuating angle, with the two positions located at 10:30h and 12h. The key can be removed in the O position, and special lock configurations including SB31, 421 and 455 are possible.

What Is Siemens 3SU10004BC010AA0 Used For?

The Siemens 3SU10004BC010AA0 RONIS key-operated switch is designed for applications where a machine function needs to be controlled through a key and the command should operate temporarily rather than remain mechanically latched.

The two switch positions are O and I. The key is turned through a 45° actuating angle between the two positions.

Because this is a momentary contact type, the switching action is intended to be temporary. The exact electrical behavior depends on the compatible contact module and the machine's control circuit.

The key-operated design can help restrict operation of the associated function to personnel who have access to the appropriate key.

Siemens 3SU10004BC010AA0 for Industrial Control Panels

The Siemens 3SU10004BC010AA0 key-operated switch provides a compact operator-control solution for industrial electrical panels.

Its 22 mm round mounting format allows it to be installed in standardized control-panel layouts alongside compatible Siemens SIRIUS ACT pushbuttons, selector switches, indicator lights and emergency-stop devices.

The key-operated mechanism adds controlled access to the associated machine function. This can be particularly useful where an operator command should not be accessible through a conventional pushbutton alone.

Because the device uses momentary operation, it can be used for temporary control commands rather than functions that require a permanently maintained mechanical position.

O-I Two-Position Key Switch

The switch provides two positions:

• O – centre position
• I – actuated position

The positions are arranged at 10:30h and 12h, with a 45° actuating angle.

The key-operated design allows the operator to turn the switch from O toward I to generate the required control action.

Since the product is a momentary contact type, the exact behavior after the key is released should be considered together with the associated electrical contact module and control circuit.

Momentary RONIS Key Switch

The momentary contact design differentiates the 3SU10004BC010AA0 from mechanically maintained key-operated switches.

A momentary key switch can be useful when a key is required to authorize a temporary command, such as:

• Machine command
• Control activation
• Special function activation
• Maintenance command
• Manual operation command
• Equipment control
• Automation-system command
• Authorized operator function

The exact purpose should be determined by the machine manufacturer's control philosophy.

Key Removal in O Position

The key can be removed in the O position.

This allows an authorized operator to return the switch to its O position and remove the key. The key can then be stored or controlled separately, helping prevent unauthorized operation.

For applications involving machine safety, however, the key switch should be considered as part of the complete engineered control system and should not be treated as a standalone safety device.

RONIS Lock Number SB30

The standard lock configuration for the 3SU10004BC010AA0 is SB30, and the product is supplied with 2 keys.

The lock number is important when replacing an existing RONIS key switch because the replacement needs to match the intended key arrangement.

The product specification also indicates possible special lock configurations:

• SB31
• 421
• 455

For replacement orders, always verify the complete ordering code and required lock number.
