A rotary switch is a type of mechanical switch in which a set of contacts is arranged in a circular pattern around a central rotating spindle. The 71MB30-02-1-08N is a rotary switch designed to handle high currents, up to 250 amps at 600 volts AC, and meet applicable requirements of UL and CSA. It is designed for applications in multi-speed motors, variable frequency drives (VFD), and other variable speed applications.

The 71MB30-02-1-08N offers a variety of features to ensure reliable operation in harsh industrial environments. The contacts are made of a silver alloy to reduce electrical resistance and assure a long service life. The hard wearing insulator and case are made from an industrial-grade acetal plastic, providing excellent weather, chemical and noise resistance. The contact pattern is precision milled ensuring low wear and minimal arcing even at high current loads. The case has two mounting flanges for easy attachment to chassis or other surface.

The 71MB30-02-1-08N works on the principle of switching a current between two or more positions. When the spindle or cam is rotated to one position, the contacts close and current flows. When rotated to a different position, the contacts open and current is interrupted. The number of positions available on the switch is determined by the number of contacts. The 71MB30-02-1-08N has 8 positions available, each with a single contact.

The 71MB30-02-1-08N is primarily used in industrial applications such as machinery, control panels and security systems. It is ideal for applications requiring precise control, such as voltage regulation or phase control. It can also be used as an emergency stop switch in applications such as elevators or lifting equipment. Other applications include speed control of fans and motors, machine tool control and limit switches.

The 71MB30-02-1-08N is a reliable and robust switch, designed for long life and rugged use. It is suitable for harsh industrial environments and carries a UL, CSA and CE safety rating. With its precision milled contacts, robust construction and up to 250A switching capability, it is an ideal solution for a variety of industrial applications.
