Electric tool switching (343409980) with variable speed control (0–2800 RPM), specifically engineered for SBE650, BE561, and BE560 to deliver reliable power regulation in high-load applications. Key benefits Precise speed control: Variable 0–2800 RPM output lets you match torque and speed to the task for controlled drilling and fastening under heavy load. Reliable in harsh conditions: Sealed, water-resistant construction prevents debris intrusion and maintains stable operation in dirty or damp jobsite environments. Long-lasting industrial switching: Pressure-sensitive ergonomic button and industrial-grade switch mechanism have been tested to exceed 50,000 clicks for consistent performance over time. Built for compatibility: Designed specifically to replace or upgrade switching on SBE650, BE561, and BE560 models (part number 343409980). What this solves Eliminates inconsistent power delivery when switching between tasks, reducing work interruptions and tool stress. Keeps the switching mechanism protected from dust, concrete particles, and moisture that commonly cause failures on construction sites and workshops. Provides a durable, repeatable control interface that holds up through frequent use and demanding conditions. Typical applications Concrete drilling on construction sites where variable speed and debris resistance are required. Furniture assembly and renovation work that needs controlled torque for repeatable results. Mechanical repairs and home workshop projects where a durable, water-resistant switch helps reduce downtime. Compatibility and performance summary Part: 343409980 Compatible models: SBE650, BE561, BE560 Speed range: 0–2800 RPM (variable) Durability: Industrial-grade switching rated 50,000+ actuations Construction: Sealed, water-resistant design with pressure-sensitive ergonomic button For professionals and serious DIYers who require precise speed control and durable switching in construction, renovation, and workshop environments.
