Core Features 2-Position Maintained Pushbutton for Control Circuits: Functions as a 2-position maintained-contact pushbutton switch designed for manual control of industrial circuits (e.g., starting/stopping auxiliary equipment, selecting operating modes, or activating/deactivating control functions). The “maintained” mechanism means the switch stays in the pressed position until manually toggled back—unlike momentary switches that reset when released—making it ideal for setting persistent states (e.g., “Machine On”/“Machine Off” or “Auto”/“Manual” modes). Low-Voltage Control Compatibility: Rated for AC 230V (50/60Hz) and DC 24V (standard industrial control voltages), with a maximum switching current of 6A (resistive load) and 2A (inductive load). It features a single-pole double-throw (SPDT) contact configuration (1 normally open/NO + 1 normally closed/NC), supporting flexible circuit design—for example, using the NO contact to energize a “Run” circuit and the NC contact to de-energize a “Standby” circuit when toggled. Flush-Mounted Design for Space Efficiency: Features a flush-mount housing (22mm standard panel cutout) that sits nearly flat against control panel surfaces, reducing the risk of accidental activation (e.g., from bumping or debris) and creating a streamlined, professional appearance. The housing is constructed from flame-retardant thermoplastic (UL94 V-0) with a smooth, easy-to-clean surface—suitable for installation in control cabinets, machine dashboards, or production line control panels. Durable Construction & User-Friendly Operation: Actuator: A high-impact plastic pushbutton with a tactile “click” feedback to confirm position changes, ensuring users can feel when the switch toggles between states. Contact System: Silver-plated copper contacts for low resistance, minimal arcing, and long-term reliability (≥100,000 mechanical operations). Ingress Protection: Meets IP65 protection (IEC 60529) to resist dust ingress and low-pressure water jets—safe for use in workshops, manufacturing floors, or areas with occasional washdowns. Color-Coded for Visual Safety: The pushbutton actuator is yellow (a standard color for “warning” or “mode selection” in industrial settings), improving visibility and helping operators quickly identify the switch’s function—critical for reducing human error in busy control environments. Global Compliance & Interoperability: Meets international safety and performance standards including IEC 60947-5-1, UL 508, and CSA C22.2 No. 14, ensuring compatibility with global industrial control systems. It fits standard 22mm panel cutouts, making it easy to retrofits into existing control panels or integrate with Siemens SIRIUS® control systems. Typical Applications The Siemens Switch 3SU1002-2BF60-0AA0 is engineered for manual maintained control of industrial circuits, with core use cases including: Auxiliary Equipment On/Off Control: Used to toggle power for small auxiliary equipment (e.g., cooling fans, lighting, or sensors) in machine control panels. The maintained position ensures the equipment stays on/off until intentionally changed, preventing accidental shutdowns or startups. Operating Mode Selection: Deployed to select between operating modes (e.g., “Auto”/“Manual” for conveyor systems, “Local”/“Remote” for pump control) in manufacturing lines. The SPDT contacts enable seamless switching between two circuit paths, supporting mode-specific functionality. Emergency Auxiliary Control: Installed as a secondary control for critical but non-safety functions (e.g., activating/deactivating a product sensor or adjusting a feed rate). The flush design reduces accidental activation, while the tactile feedback ensures operators confirm mode changes. Control Panel Status Setting: Integrated into central control panels for setting persistent states (e.g., “Line Active”/“Line Inactive” or “Production”/“Maintenance”). The yellow color helps operators quickly locate the switch among other controls. Commercial & Industrial Appliances: Used in commercial equipment (e.g., industrial ovens, packaging machines, or material handling tools) to toggle between operational states. The IP65 rating ensures reliability in environments with dust or occasional moisture.
