Rotary Switches

Rotary switches are versatile electronic components which are used in a variety of applications in numerous industries. These switches work by rotating a switch shaft to move the switch from one position to another, opening or closing electrical contacts. The 44M30-05-1-03N rotary switch is a single-pole double-throw (SPDT) variation with three positions.

Application Fields

The 44M30-05-1-03N switch is commonly used for changing between stages of electronic circuits and providing alternative pathways for signal routing. It is often used in electrical appliances, automotive systems, audio-video equipment and computer accessories. This rotary switch is also employed as a selector switch, allowing users to choose between different settings of an appliance, such as the speed setting of a fan, the temperature setting on a heater, and the mode setting on an air conditioner.

Working Principle

The 44M30-05-1-03N switch consists of an encoded shaft attached to a knob or dial, and an actuating cam in the form of a disc with teeth. When the knob or dial is rotated, the cam is also turned, making or breaking electrical connections. When the switch is in the neutral or off position, the cam does not engage any of the contact arms, leaving them free to rotate. Pressure from a spring-loaded pin is used to hold the contact arms in a fixed position when the switch is in any of the two on positions.The contact arm assemblies are made of conducting metal, such as copper or brass, and the center contact arm is insulated from the outer contact arms. This arrangement ensures that the current will only be conducted from one of the outer arms to the center arm. The type of material used for the conducting contact arm determines the amount of current that can safely be allowed to pass through the switch. The 44M30-05-1-03N switch has a nominal rating of 10A at 125/250VAC.

Final Remarks

The 44M30-05-1-03N is a simple and robust solution for controlling electrical circuits. It is commonly used in consumer electronics, automotive, and industrial applications and is relatively inexpensive compared to other types of switches. Moreover, the switch can be easily replaced and adjusted, making it a reliable solution in both consumer and industrial applications.
