Selector Switches
In industrial control systems, selector switches are widely used and highly practical components that allow operators to switch between two or more operational modes. Unlike standard push buttons that perform a single action, selector switches provide greater flexibility and control by enabling multiple functions based on the rotation angle or switch position.
Selector switches are typically rotary in design, operated by turning the knob clockwise or counterclockwise. They feature clearly defined positions or detents—such as Manual / Automatic, Start / Stop / Standby, or Main / Auxiliary Control—to indicate each selected mode. Some models may also include illumination or key-lock functions to enhance visibility and security.
These switches are commonly found on machine control panels, power distribution boards, elevator systems, and equipment interfaces, making them ideal for mode selection and multi-function control. With proper configuration, selector switches can simplify operation workflows, improve system flexibility, and enhance overall reliability.
The video below demonstrates real-world examples and internal mechanisms of selector switches. Feel free to watch for a deeper understanding of their applications and selection criteria.
