Product Overview

The Siemens 3SB3 is an industrial operator-control series designed for electrical control panels, machinery interfaces, and industrial automation applications.

This assembly features a 22mm flush blue pushbutton paired with a Siemens 3SB3403-0A contact block, identified with a 1NO + 1NC contact configuration.

Pushbutton switches provide manual electrical control by changing the state of connected contacts when the actuator is operated. They are commonly used for machine control, equipment operation, signaling, and control circuit functions.

The normally open (NO) contact is open in its normal state and closes when actuated, while the normally closed (NC) contact is closed in its normal state and opens when actuated, according to the switch mechanism.

The 22mm mounting format is widely used in industrial operator stations and control panel assemblies. The flush blue actuator provides a compact and easily identifiable operator interface.

This Siemens pushbutton assembly is a practical replacement option for compatible industrial machinery, electrical control cabinets, manufacturing equipment, and maintenance applications requiring the specified configuration.
