A rotary switch is an electrical device that incorporates a circular handle or knob that can be rotated to open or close an electrical circuit. The 71BDF30-05-1-AJN is a multiposition rotary switch that is widely used across various industries due to its reliable performance and relatively low-cost production. This particular switch series is designed with a total of five rotary positions as well as two actuator positions and can be used to control electrical loads of up to 20A.

In order to understand this switch’s application field and working principle, the following will provide a brief overview. This switch series finds use in multiple industries, including aviation, medical, telecommunications, power distribution, construction, and industrial automation. These switches have the ability to withstand hazardous environmental conditions and are considered highly reliable and durable. The 71BDF30-05-1-AJN switch series is also compliant with RoHS standards.

Before looking at how this switch works, its components must be examined. Generally, the 71BDF30-05-1-AJN switch includes a rotary knob, actuator plate, contact arm, contact blade, and contact elements. The actuator plate is usually made of sheet metal and the contact arm, contact blade, and contact elements are usually made of brass or stainless steel. All of these components are assembled together and secured with a fixing nut.

While this switch is available in both single-pole and double-pole versions, the single-pole version functions as a single-pole, double-throw rotary switch. This means that the switch can open or close two circuits with a single knob. The double-pole version can open or close two separate circuits with two separate knobs.

The main function of the 71BDF30-05-1-AJN rotary switch is to change the contacts of an electrical circuit. This switch works by rotating the knob of the switch to any of the five available positions. As the knob is rotated, the actuator plate causes the contact blade to open or close different relationships with the contact element and the contact arm. This changes the position of the contact in the circuit and thereby controls the electrical current in the circuit.

This multiposition switch series also has two actuator positions which are used as auxiliary contacts. In addition to the five main positions, these contacts can be set to “on” or “off” and can be used to activate low-profile loads such as LEDs and relays. These auxiliary contacts can be used in conjunction with the five main positions to provide a wide range of functions.

The 71BDF30-05-1-AJN series of rotary switches offer reliable performance, excellent versatility, and, in many cases, relatively low cost. Although the switch requires a small number of components, careful consideration should be taken when selecting a switch for a particular application. The various components of the switch must be carefully examined in order to ensure that the switch will be able to withstand the environmental conditions it will be exposed to and that it will be able to reliably perform its intended function.
