Introduction of Rotary Switches

Rotary switches are devices that, when manually triggered, interrupt or complete a circuit, allowing current to pass through. Typically made out of metal, they come in a variety of shapes and sizes to accommodate a wide range of applications.Common uses of rotary switches include making and breaking circuits, establishing multiple connection points, and controlling audio equipment. Most are single-pole switches, meaning they only have one set of two terminals, often called \'poles\' to connect or disconnect.Although their invention dates back to the 19th century, the rotary switch is still a popular device with plenty of practical applications, including modern electronic and computerized items.

44M45-03-1-05S Application Field and Working Principle

The 44M45-03-1-05S rotary switch is designed for use in general-purpose applications, such as in light and power control, audio mixing and switching, frequency selection, controls for door buzzers, and event control systems. It can also be used in machine tools, lighting systems, automated production equipment, industrial automation and a variety of other tasks.The 44M45-03-1-05S rotary switch is a 5-position, single-pole switch with a single-section, non-shorting design. It also features a dielectric strength rating of 250VAC/500VAC and a contact rating of 6A/125VAC and 3A/250VAC.These rotary switches feature an insulated plastic case and a strong electrical contact configuration ensuring they will not short out when the switch is in use. The switch is available in both knurled and flat shafts with a choice of shaft lengths and terminals.When triggered manually, the knob in the switch causes a contact arm to rotate and make contact with the terminals. This allows current to pass through, thus creating a circuit, which is then interrupted when the contact arm is rotated back. The 44M45-03-1-05S rotary switch is designed with a long life of up to 30,000 operations and is ideal for high-frequency switching applications. The parameters for these switches include a contact resistance of 50mΩ (maximum) and an insulation resistance of at least 1,000MΩ at 500VDC, operating temperature –20°C to +75°C and a mechanical operating life up to 30,000 operations at the rated load.

Conclusion

The 44M45-03-1-05S rotary switch is a high-quality device designed for use in a variety of applications. Due to its long life, high dielectric strength rating, and consistent contact configuration, it is a great choice for any application requiring reliable and precise operation.
