Rotary switches are commonly employed as switching devices in industrial, telecommunications and consumer applications. Designed as quick action, "On/Off" type switches, they offer the user the ability to engage or disengage circuits with a single switch action. The 71BDF30-05-2-AJS is a medium-duty, two-position rotary switch that is used in a wide variety of applications. This article will explore the application field and workings of this switch in detail.

What is a 71BDF30-05-2-AJS Rotary Switch?

The 71BDF30-05-2-AJS is a two-position, medium-duty, rotary switch with a maximum current carrying capacity of 30 amps (AC) and 13 amps (DC). It has four contact poles, each with one set of normally open and normally closed contacts. The rotor is made of plated diecast zinc, while the frame and contacts are made of brass. The switch also features a white marking disc, pre-wired leads, and a dust-tight seal, making it suitable for use in locations where there is exposure to dust and dirt.

Uses of the 71BDF30-05-2-AJS Switches

The 71BDF30-05-2-AJS switch is a versatile and highly reliable switching device suitable for a wide range of applications. Due to its dust-tight construction, it is particularly well suited for locations where dirt, dust, and moisture might cause problems. Examples include farm equipment, beachside and marina equipment, motors, appliances, lighting fixtures, and garage door openers.

The two-position design of the 71BDF30-05-2-AJS is also extremely useful for control circuits and other applications that require resetting the circuit to a specific setting. The switch is highly reliable and durable, making it an excellent choice for use in safety-critical applications, such as motor controllers and equipment used in hazardous environments.

The Working Principle of 71BDF30-05-2-AJS Switches

The 71BDF30-05-2-AJS is a rotary switch, which means that it operates by rotating a small disc (known as the rotor) with two positions. When the switch is in the "On" state, the rotor turns to a specific angle, completing the circuit and allowing electricity to flow. When it is in the "Off" state, the rotor is rotated to a different angle, breaking the circuit and preventing electricity from flowing.

The rotor is connected to an external knob or lever, which allows the user to easily engage or disengage the switch. The 71BDF30-05-2-AJS switch also typically includes an intermediate contact, which ensures that the circuit is completely disengaged in the event of a power surge or failure.

Conclusion

The 71BDF30-05-2-AJS is a versatile, medium-duty rotary switch that is suitable for a wide range of applications and environments. It features a two-position design, four contact poles, and a dust-tight seal that makes it particularly well suited for locations where dirt, dust and moisture might be present. In addition, the 71BDF30-05-2-AJS is highly reliable and durable, making it an excellent choice for use in safety-critical applications.
