Rotary Switches are one of the most versatile and widely available switch types. The 51KPT30-01B11N is an example of a rotary switch, and its application field and working principle are outlined below.

Application Field

The 51KPT30-01B11N rotary switch has two common applications. The first is in motor vehicle ignition systems, where they are used to control high current circuits. This includes engine ignition, starter voltage and lighting control. The second application is in consumer goods and electrical appliances, where they are used to control electrical loads such as fans, pumps, lights and motors.

The 51KPT30-01B11N rotary switch is also suitable for other industrial, commercial, and telecommunications applications where high current switching is required.

Working Principle

The 51KPT30-01B11N rotary switch is a three-position switch. It has three positions: On, Off, and Neutral. When the switch is in the On position, the three contacts, A, B and C, establish a connection between the two terminals. When it is in the Off position, no connection is established between the terminals, and when the switch is in the Neutral position, the contacts remain disconnected.

The 51KPT30-01B11N rotary switch features a unique skirt that surrounds the switch arm to reduce wick away of the switching action caused by vibrations. This makes the switch very reliable and reduces wear on the switch arm. The switch also features an adjustable upper stop that prevents the switch arm from being dialed too far and causing damage to the contacts.

The 51KPT30-01B11N rotary switch is an ideal choice for high current switching applications such as motor vehicle ignition systems, consumer goods and electrical appliances, industrial and commercial use, and telecommunications. It is reliable, durable, and simple to use.
