Differences Between a Rotary Switch and a Regulator

Rotary switches

Rotary switches are multi-functional electromechanical devices that, as the name suggests, rotate clockwise or counter-clockwise to control the connected equipment. They are the human-machine interface component and are generally referred to as single poles and double poles. Poles and throws are the major configurations of the air cooler rotary switch. These poles are related to the number of circuits that are being controlled by the switch. And the throw defines the number of positions that the air cooler rotary switch poles can be connected to. 

A rotary switch for cooler is a great alternative to a push-button switch. They are operated by rotation. The cooler rotary switch can be moved to the next position using a rotating pin inside which allows the cap to rotate. They are generally used when a device needs more than a two-position control switch. For example, a CB radio with numerous frequencies of reception or several radio channels.

The biggest advantage of opting for single cooler rotary switches is that they can be utilized in industrial settings to control a diverse range of circuits or controls with just a switch. They are often employed with circuitry that needs to move seamlessly between several complex configurations. 

The fundamental design pattern of a rotary switch for a cooler will consist of a spindle or rotor with a protruding spoke.  The spoke changes its position when the spindle is moved. It contacts the electrical terminal and activates the associated circuits or changes the electrical states. And the circuits travel through the wafer. The air cooler rotary switch terminal is usually located around the spindle at specific rotational intervals. 30, 45, 60, and 90 degrees determine the number of switch positions available. 

Several applications of the cooler rotary switches can be found in industrial, medical, construction, and military communication devices. Rotary switches are extensively used to adjust the speed of conveyor belts, change the frequency of oscilloscopes, and control diagnostic medical devices. Rotary light switches, rotary lamp switches, and dimmers are some of the well-known applications of rotary switches. 


A regulator is composed of resistors that help in controlling the voltage as well as decreasing and increasing as per the requirement. For the power supply to provide a constant output voltage, without taking the input voltage variation or load current variation into consideration, there is a need for a regulator.  

With a regulator device, you can control the air cooler speed as well as accelerate or reduce the electrical current. On top of that, with the help of 3 phase coil, slow, medium, and high speeds can be attained. The regulator saves electricity by minimizing the speed but loses it by being heated when voltage is decreased. 

Regulators are extensively used in all power supply systems to regulate voltage and save the device from serious damage. It is also used in electronic circuits to deliver a precise amount of voltage.
