Rotary Switches

Rotary switches, such as 423511-2-03S, are electrical switches which control the connecting or disconnecting of a circuit by rotating either a knob or a lever expanding its selection of options. This type of electrical switch is found in many applications, ranging from basic household devices to far more advanced industrial uses.

Application Field

423511-2-03S rotary switches can typically be found in a variety of settings. Home appliances incorporating these switches include washing machines, refrigerators and cookers. In a professional setting, these switches are used in security systems, medical equipment, and alarm systems. The flexibility in the way these switches can be used makes them ideal for many applications.

Working Principle

In a 423511-2-03S rotary switch, the knob or lever is used to rotate a contact arm in order to make or break connectivity in the circuit. This action is usually accomplished using a series of gears which interact with the knob or lever as it is rotated. The contact arm is usually made of metal, while the gears are typically constructed of plastic.

The contact arm rotates around a common point, known as the center point. As it moves around the center point, it either touches or breaks contact with the various points of contact connected to the circuit. When the arm touches a contact, a connection is made and when the arm passes over a contact, the connection is broken.

Depending on the number of points of contact available, a rotary switch can can offer a wide range of options. For instance, a 423511-2-03S rotary switch is rated for up to three positions and can be used in different configurations (e.g., center off, two-way, three-way, etc.).

Conclusion

Rotary switches, such as 423511-2-03S, are extremely versatile pieces of hardware that can used in numerous applications in both industrial and domestic settings. In a rotary switch, a contractor arm is rotated around the switch\'s center point to either make or break contact with other points in the circuit. Depending on the number of points of contact, a rotary switch can offer a range of options.
