A rotary switch is a switch that has a knob or lever, and a ganged set of contact around its circumference. Rotary switches are commonly used to switch low power AC signals, often for selecting between multiple audio inputs. Commonly referred to as "knob switches", the 312-3T2E is one such switch and is used in various industrial and commercial applications.

The 312-3T2E has three contact points, with two ‘on’ positions and one ‘off’ position. These contact points are replaced by two terminals, which are located on the outside of the switch, allowing the switch to be connected or disconnected from the circuit. The switch also has three terminals to connect the switch to the circuit.

The 312-3T2E works by opening and closing its contacts when the knobs are turned. It connects the three terminals to the two on positions and one off position. When the switch is turned, it opens and closes the contacts in the desired position. The contacts are opened or closed by opening or closing a small circuit between the terminals or by connecting or disconnecting the terminals from the circuit.

The 312-3T2E is often used in many industrial and commercial applications. The two ‘on’ positions are used to select between multiple audio inputs, to switch between low voltage AC signals, and for other applications that require switching. The switch is also used in various domestic applications, such as controlling audio systems, controlling lighting, and controlling power supplies. The switch is also used in medical applications, such as controlling medical equipment, controlling blood pressure monitors, and controlling patient monitors.

In addition to industrial and commercial applications, the 312-3T2E is also used in consumer electronics. It is used to control audio systems, to control television sets and other TV components, and to control gaming consoles. In addition, the switch can also be used in automotive applications, such as controlling car stereos and radio systems.

In summary, the 312-3T2E rotary switch is a versatile and reliable switch that is used in a variety of industrial and commercial applications, as well as in consumer electronics and automotive applications. It has three contact points and two on positions and one off position. It works by creating a circuit between the terminals, or by connecting and disconnecting the terminals from the circuit. The switch is used for a variety of applications, including controlling audio systems, controlling lighting, and controlling power supplies.
