Introduction

A12505RNCBF is a type of rotary switch. Rotary switches are electromechanical devices that allow for the switching of two or more electrical circuits by rotating a knob or a lever to a different position. Rotary switches are used in many applications such as industrial process control applications, home and consumer electronics, medical, and rotary encoders.

A12505RNCBF rotary switch

The A12505RNCBF rotary switch is a medium-duty switch rated up to 480VAC. It has a silver-plated brass contact that is suitable for use on both AC and DC load circuits. The switch is UL, CSA, and VDE approved. The A12505RNCBF rotary switch is available in two models: the SP (single pole) and DP (double pole). The single pole switch has two contacts and the double pole switch has four contacts. Both models are offered with a 1/4 inch round shaft or a 1/4 inch square shaft, and come in several contact configurations and constructions. The A12505RNCBF rotary switch is designed for applications requiring a rugged and durable switch. It is designed for use with a wide range of temperatures and is resistant to shock and vibration. It is also designed to be dust- and water-proof, ensuring its use in a wide range of applications.

Application Field

The A12505RNCBF rotary switch is suitable for use in a wide range of industrial and commercial applications. It can be used in industrial process control applications such as on/off and dimmer control systems. It can also be used in HVAC systems, lighting systems, and medical equipment.

Working Principle

The A12505RNCBF rotary switch consists of a switch body, a rotor, and a contact bridge. When the rotor is rotated, the contact bridge moves across the commutator. The commutator is designed to make contact with the desired number of contacts in the contact bridge. Depending on the position of the contact bridge, momentary, latching, or keyed contacts can be made. When the rotor is turned, this changes the position of the contact bridge. The contact bridge is designed so that when the contacts are made, either a closed or an open circuit is established. This allows the switching of one or more electrical circuits.

Conclusion

The A12505RNCBF rotary switch is a medium-duty switch rated up to 480VAC. It is designed for use in a range of industrial and commercial applications, and is resistant to shock and vibration. The switch uses a rotor and contact bridge to establish electrical circuits, allowing for the switching of two or more electrical circuits by rotating a knob or lever.
