Type K motor starting switches provide manual “on-off” control of single- or three-phase AC motors, where overload protection is not required or is provided separately. Compact construction and a 600 volt rating make these switches suitable for a wide range of industrial and commercial uses. Typical applications include small machine tools, pumps, fans, conveyors, and many other types of electrical machinery. They may also be used on non-motor loads such as resistance heaters.
