    • Public Safety – Pushbutton switches are used to activate emergency response systems such as fire alarms and traffic lights.

    Working Principle:

    Pushbutton switches operate by mechanical actuation. When a button is pressed, an electric circuit is completed, resulting in current flow. The current flow activates a connected device or system, such as a relay, actuator, or motor. When the button is released, the circuit is broken and the connected system or device is deactivated.

    The KS11R21CQD Pushbutton Switch is able to provide reliable operation in a wide range of applications. It is designed with a anti-rotation mechanism and a water-resistant rating of IP67, allowing for reliable operation in areas that require extra protection from water and other elements. Additionally, the KS11R21CQD Pushbutton Switch is UL, CSA, and VDE approved, making it suitable for usage in a variety of different applications.

    Conclusion:

    The KS11R21CQD Pushbutton Switch is a reliable and robust electric switch that is suitable for use in a variety of application fields, including access control systems, environmental control, medical equipment, hazardous areas, telecommunications, and public safety. It is designed with a anti-rotation mechanism and a water-resistant rating of IP67 and is UL, CSA, and VDE approved, making it reliable and highly adaptable for all sorts of applications.
