Rotary Switches

A Rotary Switch (44MG45-04-1-05S) contains an array of contacts that are changed by the rotation of the switch actuator. The contacts can be configured to suit many different switching applications. Its actuator can be controlled either manually or automatically. The use of Rotary Switches can be found in many industries, including control panel, medical equipment, telecommunications and instrumentation.

Application fields

• In control panel, Rotary Switches are widely used to switch on or off power. Typical examples will be found in motor control, machine control panel and instrument control.
• In medical equipment, Rotary Switches are used to manage electrical power distribution and control. Rotary Switches are usually found in operating tables and healthcare equipment.
• In telecommunications, Rotary Switches are typically found in two-way radios and cell phones. They provide the switching function needed to connect components and can also select different power levels.
• In instrumentation, Rotary Switches are used to select test parameters or data points. They are often found in test and development instruments such as oscilloscopes, signal generators and frequency meters.

Working principle

Rotary Switches work by changing the position of the contacts that are assembled in a pre-determined pattern on the circuit board. When the actuator is rotated, the contacts move to the position where they make contact. This change in contact position can provide a signal to other circuit elements such as transistors, light emitting diodes, relays, motors and solenoids. It can also be used to switch the power supply on or off.

Conclusion

44MG45-04-1-05S Rotary Switch is a versatile device that can be used for a variety of applications. Its actuator can be manually or automatically controlled and its contacts can be used to provide a signal or switch power on or off. Its use is wide spread in the field of control panel, medical equipment, telecommunications and instrumentation.
