S800 series snap-action switches have been proven since decades and are used worlwide.
S800 Series snap-action switches feature positive opening operation, which guarantees a reliable opening of NC contacts, even when welded due to a short-circuit or current overload. That is why S800 Series snap-action switches are particularly suitable for applications where safety is a prime requirement.
The snap mechanism for which Schaltbau‘s switches are renowned ensures rapid switching of high electrical loads. The switches are of compact design and will fit in the most confined spaces.
Features
- Positive opening operation: Reliable interruption even after contact welding, in compliance with IEC 60947-5-1, Annex K
- Double break contacts: High electrical rating due to solid contact bridge and double break contacts
- Precision switch: High switching accuracy and resistance to shock and vibration
- Magnetic blowout: Optional blowout magnets to extinguish the arc at higher DC loads
- Sealed to: IP40 in accordance with IEC 60529
- Contact material: Silver or gold
Applications
- Limit switches for machine, door and plant control systems
- Switches for driver‘s cab of rail vehicles and control panels in cranes
- Auxiliary switch for automation tasks
- Safety limit switch in control panels and electrical installations
