Rotary switches are a type of electrical switch wherein the operation of the switch is achieved by rotating a contact connected to a metal surface on a galvanized post. The rotary switch is useful in electrical circuits that require a particular type of switch operation, such as the delivery of current to a power circuit when the switch is rotated. There are several types of rotary switches, including 312-3 application field and working principle.

312-3 rotary switches are commonly used in industrial, medical, and home appliance applications. This device is specifically designed to enable silent and smooth switching with a high resistance to vibration and shock. It is typically composed of four poles, with each pole providing 12 possible switch positions. This allows the rotary switch to be used in a wide range of applications, from low-power devices such as coffee machines to highly sensitive laboratory and medical equipment.

The working principle of the 312-3 rotary switch is based on the rotation of the contact from one position to another. When the contact is rotated, it comes into contact with two metal surfaces that are connected to two different electrical circuits, either providing power to or taking power from the circuit, depending on the direction of the rotation. This allows for the control of the flow of electrical current within the circuit without any direct contact with the switches.

In addition to the aforementioned applications, 312-3 rotary switches are also commonly used in motor control, sound reproduction, light-sensitive electronic circuits, and general-purpose electronic circuits. For example, they can be used to control the speed of motors, to select the sound frequency of an audio system, and to control the intensity of an LED display. In addition, these switches can also be used to switch between multiple lights in a room.

The use of 312-3 rotary switches is not limited to simple applications, as they can also be used in more complex systems. For example, they can be used to control multiple functions within a single circuit, such as regulating the volume and frequency of an audio system. In addition, this type of switch can also be used to control a security system, allowing for the ability to adjust the motion sensor or sound detection settings within the circuit.

With its wide range of applications and its ease of use, the 312-3 rotary switch can be a great addition to any number of circuits, from audio systems and security systems to home appliances and industrial equipment. Furthermore, its resistance to vibration and shock makes it well suited to use in many rugged and extreme working environments. The 312-3 rotary switch is a versatile and reliable choice for a wide range of applications.
