Rotary switches are used in many applications that involve the selection of an output circuit by manually rotating the switch spindle, such as lighting and audio systems. 71C301112NF-1112NF is a two-pole, two-position rotary switch. It is mainly used for lighting and sound equipment. This article will discuss the application field and working principle of this rotary switch.

The first application field for the 71C301112NF-1112NF switch is to control the lighting system. It can be used for low voltage lighting systems, such as lamp lighting systems, decorative lighting systems, signal lighting systems and display lighting systems. The working principle is to use the spindle as a moving contact, and to rotationally connect the fixed contact with the changing contacts according to the different angular positions of the rotating contact arm. The contact material can be copper or silver alloy, which can achieve higher switching performance. And its wiring terminals are suitable for stranded conductor and are screw-mounted with clips.

The second application field for the 71C301112NF-1112NF switch is to control the audio system. It is mainly used for 2-channel or 3-channel three-way system to switch two sets of stereo routes. The contact material adopts silver alloy and gold plating process, which can reduce contact resistance and make the transmission of audio signals steady, clear and of high fidelity. The contacts move or turn along a helix line, which is stable and reliable, and will not generate any leakage or noise.

The working principle of the 71C301112NF-1112NF switch is mainly driven by the switch spindle. When the switch spindle rotates to the corresponding angle, the rotation movement of the spindle can make the pair of independent changeover contact stable contacts, so as to realize the connection and disconnection of the line. In different switch positions, the pin on the spindle can move back and forth within the eccentric slot on the contact arm to complete the connection and disconnection of the contact circuit.

To sum up, the 71C301112NF-1112NF switch is a two-pole, two-position rotary switch. It can be used to control the lighting system and audio system. Its working principle is mainly driven by the switch spindle and the rotation movement of the spindle can make the pair of independent changeover contact stable contacts. It is stable and reliable, and will not generate any leakage or noise.
