This document provides specifications for a high tension rotary switch. The switch has a dielectric withstand of 15 kV between contact to contact and pole to pole. It has a continuous current rating of 50 A and can handle momentary currents of up to 1,000 A for 10 cycles and 5,000 A for capacitor discharge of 20uS. The contact resistance is a maximum of 1.0 mΩ and it operates between -40C to 65C. The switch has heavy silver plated contacts, positive stops, safety interlocks, and is durable for extreme conditions.
