What Is A Rotary Switch?

A rotary switch is a switch that switches contact points by turning.
Rotary switches are used for volume control of audio components, knobs of microwave ovens, etc. Most rotary switches are used to switch multiple contacts, but they are sold with only one contact. Most rotary switches are used to switch multiple contacts, but switches that switch only one contact are also available. Recently, ultra-compact rotary switches have been developed, contributing to the miniaturization of audio equipment and other devices.

Rotary switches are used in a wide range of applications, from familiar home appliances to industrial equipment.

Applications For Rotary Switchs

  • Volume control of audio components
  • Setting the output of microwave ovens
  • Switching power and strength of electric fans
  • Switching the volume of measuring machines and communication equipment
  • Switching of control board settings for inverters, air conditioners, etc.
Recently, pendant lights that use a single-contact rotary switch to operate the power supply are also available to create a retro atmosphere. Also, in recent years, they are sometimes used as power switching switches for portable LED lighting as part of DIY projects.

How To Use A Rotary Switch?

Rotary switches are used to switch circuits by rotating the actuator. They are often used to set up digital circuits. They are used when the switching frequency is not high, for example, for setting purposes.

There are various types of rotary switches, such as those with flat actuators or shaft-shaped actuators. Depending on the shape, some products can be operated with a finger, while others require a screwdriver or similar tool.

  • Q What is Potentiometer?

    A

    A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.[1] If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

    The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.

    Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
