About  Keylock Switches

Keylock switches, as a type of electromechanical device, are employed to control the flow of current within an electrical circuit, allowing for the initiation or cessation of current flow through the activation of a key-based actuator. These switches are characterized by their utilization of a physical key as the actuating mechanism, which can be rotated along the center axis to different stopping positions, typically ranging from 2 to 12 distinct positions. The keylock switch's design allows for precise control over the current flow, with each stopping position serving as a specific configuration or state within the circuit. Depending on the particular model, the key may be removable or non-removable at various stopping positions, providing flexibility in terms of operational access and security. These switches are engineered to accommodate a wide range of voltage ratings, spanning from 12V to 500V, and current ratings ranging from 100mA to 20A. This versatility in voltage and current specifications enables keylock switches to be utilized across diverse electrical systems and applications, catering to varying power requirements while maintaining reliable performance. When integrated into electrical circuits, keylock switches offer precise and secure control over the flow of electricity, making them suitable for applications where selective activation or deactivation is necessary. The utilization of a physical key adds an extra layer of security and control, ensuring that only authorized personnel with the corresponding key can initiate or modify the circuit's configuration. In summary, keylock switches serve as electromechanical devices that enable the controlled initiation or interruption of current flow within electrical circuits through the use of a key-based actuator. Their adjustable stopping positions, broad voltage and current ratings, and security-enhancing features make them versatile components suitable for a wide array of electrical control and protection applications.
