Introduction

A rotary switch is a switch operated by rotation. In its simplest form, it consists of a spindle or “drum switch” rotating inside a spring-loaded metal casing. A wire is attached to the spindle. As the spindle rotates, the wire moves in and out of the channels along the side of the casing, which allow electricity to be conducted from one contact to another. These switches are the easiest, most common, and most cost-effective way of switching current in low voltage (typically less than 600VAC) applications.

51KM30-01-1-09N Application Field and Working Principle

51KM30-01-1-09N is a kind of rotary switch. It is mainly used for controlling the power or switching from one circuit to another, or switching from one device to the other, like lighting, motor control, etc. It is suitable for load circuit with DC and AC 50-60HZ when working voltage lower than 750V AC or lower than 450V DC.

51KM30-01-1-09N is a type of spring-loaded rotary switch with 16 independent contact arrangements for make-and-break applications. It is designed for hand-operated switching in low to medium current ratings up to 500V. Each switch compartment is composed of stationary contacts mounted on a support base and rotatable contacts joined by a common actuating shaft, which also carries an operating lever.

A capacitor-actuated bilaminated core provides the force to actuating the rotor blade. These switches can be used in installations with a power supply up to 600 volts AC or 240 volts DC. It should be noted that this switch cannot be used as a disconnect switch. 51KM30-01-1-09N is used to switch low power circuits such as lighting and motor control.

Conclusion

In short, 51KM30-01-1-09N is a rotary switch with 16 independent contact arrangements for make-and-break applications. It is designed for hand-operated switching in low to medium current ratings up to 500V. It can be used in installations with a power supply up to 600 volts AC or 240 volts DC. It is mainly used for controlling the power or switching from one circuit to another, or switching from one device to the other, like lighting, motor control, etc.
