These new rotary tap switches can be configured for manual or motor operation, and have dual (continuous/intermittent) ratings from 100/150 to 1,600/2,400 amps at 600V and come in single, two or three-phase models. The switches are made to hold up under shock and severe vibration. They have a handle that accommodates two padlocks, nonferrous parts, an escutcheon, fire-retardant nontracking insulation, low operating torque, and high-pressure line contact. Models rated for 200 or more amps have silver-plated current-carrying parts. Models rated up to 1,000 amps have glass-fiber-reinforced bases, with fabricated bases for models rated over 1,000 amps. Modifications are available such as increased voltage and amperage ratings, angled terminals, key-interlock provisions, auxiliary switches for remote indication, an "off" position, and a mechanical-release handle.
