Built for reliability in industrial and commercial applications, the NSI 78220TS is a sturdy Double‑Pole, Single‑Throw (DPST) toggle switch featuring a robust bat-handle actuator. Designed to offer consistent ON/OFF control across two separate circuits simultaneously, it excels in motor control, lighting systems, and heavy-duty electrical panels.

Key Features

• Double-Pole, Single-Throw (DPST) – Simultaneously switches two independent circuits with a single action
• High Current Rating – Supports 20 A at 125 VAC and 10 A at 250 VAC resistive loads
• Motor-Rated Performance – Capable of handling up to ¾ HP (horsepower) at 125–250 VAC
• Bat-Handle Actuator – Brass toggle with nickel plating, 0.687″ long for easy grip and reliable operation
• Screw-Terminal Connections – Durable screw terminals provide strong, secure wiring suitable for repeated installations
• Threaded Mounting Bushing – 15/32″‑32 TPI thread with 0.465″ length ensures a firm panel installation
• UL and CSA Certified – Fully compliant with industry safety and performance standards
• Rugged Brass/Nickel Construction – Built with corrosion resistance and longevity in mind
