A rotary switch is a switch in which the contacts are changed when the switch rotates about its axis. This type of switch is common in radio controlled airplanes and cars, as well as some other electronic devices. There are several types of rotary switches, each with its own unique application and working principle.

The most common type of rotary switch is theSingle Pole Double Throw (SPDT). This switch has two outputs, with one input. When the switch is off, power is supplied to the two outputs. When the switch is turned on, power is shifted from one of the outputs to the other. This arrangement is commonly used to provide on/off control for devices such as motors, lights and pumps.

Another common type of rotary switch is the Double Pole Double Throw (DPDT). This switch has two inputs and two outputs, and it is composed of two Independent Single Pole Double Throw (ISPDT) switches. When the switch is off, power is supplied to both the outputs. When the switch is turned on, power shifts from one of the outputs to the other. This type of switch is commonly used to control two independent circuits simultaneously.

The most versatile type of rotary switch is the Four Pole Double Throw (FPDT). This switch has four inputs and two outputs, and it is composed of four SPDT switches. When the switch is off, power is supplied to both the outputs. When the switch is turned on, the position of the switch determines which of the four inputs is connected to the output. This type of switch is very useful in applications where multiple signals need to be switched between two outputs.

The last type of rotary switch is the Multi-pole Double Throw (MPDT). This switch has multiple inputs and multiple outputs, and it is composed of multiple SPDT switches. When the switch is off, power is supplied to all the outputs. When the switch is turned on, the position of the switch determines which input is connected to which output. This type of switch is commonly used to control multiple devices simultaneously.

Rotary switches are used in a wide variety of applications, from household appliances to complex industrial machines. They are available in many different sizes and configurations, and can be operated either manually or electronically. Their simple design makes them easy to install and use, and they offer a high degree of reliability and long service life.

Rotary switches are an important part of many electronic and electrical systems, and they are widely utilized in a variety of different industries. They provide an efficient and reliable means of controlling power, and they are a cost-effective alternative to traditional circuit breakers or relays.
