Rotary Switches

A rotary switch is an electrical switch with multiple positions, and can connect multiple circuits simultaneously. It consists of a circular switch body with a handle or spindle mounted on an axle, and multiple contacts arranged around its circumference. Rotary switches come in many shapes and sizes, and are used to control a variety of electrical functions. The 51P30-01-1-11N rotary switch is a two-pole, three-position momentary switch.

Application Field

Rotary switches are used in a variety of applications where the operator needs to select a single contact out of many possible contacts. Common uses of rotary switches include selection of multiple radio frequencies in radios, telephone call routing and selection of different operating modes in a variety of electronic equipment. They are also used in amplifier systems to control tone, loudness and output levels. The 51P30-01-1-11N rotary switch can be used in applications requiring a switch with a momentary action to switch between two different modes.

Working Principle

The working principle of a rotary switch is relatively simple. When the rotation handle or spindle is turned, the contacts on the switch move from one contact to another, forming a connection and breaking another connection in the process. Depending on the number of positions the switch has and the number of contacts it has, one contact can be connected to a certain number of other contacts. The 51P30-01-1-11N rotary switch can switch between two different states, such as a high and low voltage, or on and off.

The 51P30-01-1-11N has a two-pole, three-position momentary switch. This means that the switch has two poles and three positions, and the action of the switch is momentary – meaning it requires repeated movement in order to stay in it’s desired position. It is most commonly used in applications such as audio equipment and appliances.

Conclusion

The 51P30-01-1-11N rotary switch is a two-pole, three-position momentary switch that is suitable for use in applications requiring a switch with a momentary action to switch between two different modes. Typical applications include selection of multiple radio frequencies in radios, telephone call routing and selection of different operating modes in a variety of electronic equipment. The working principle of the rotary switch is relatively simple and it is a reliable and effective way of controlling a variety of functions in electronic and audio equipment.
