Snap Action, Limit Switches

Snap action, or bi-stable, limit switches are electromechanical switches that open and close a circuit when physical force is applied to the switch’s actuator. The TMCGD6ST1040C series snap action limit switch is a two-pole device with 6A (AC)/2A (DC) rated current, and 0.4N operating force. It is suitable for applications that require both reliable switching performance and repeated operation.

Application Field

TMCGD6ST1040C snap action limit switches are commonly used in construction automation, industrial control, consumer electronics, home security systems, and other areas where physical motion needs to be monitored. These devices are designed to switch on or off depending on the physical input they receive. Common applications include door and window alarms, conveyor equipment, automatic lifts, motors, and machine tools.

Working Principle

TMCGD6ST1040C snap action limit switches use an actuator to provide a physical input that or will switch contacts either open or closed. This operation is achieved by use of an enclosed spring-loaded actuator that responds to pressure or force. When actuated by an external pressure, the actuator arm moves to the preset limit and mechanically closes (or opens) the switch contacts. The contact arm requires a fixed force to keep it in place which provides the contact stability needed for reliable operation.

The TMCGD6ST1040C snap action limit switch also has an adjustable operating height. This feature enables the switch to react immediately to the smallest pressure and react the same way despite the changes in the size of the force which is pressing on it. This adjustable height allows greater flexibility and accuracy in the application.

TMCGD6ST1040C snap action limit switches offer reliable operation over a wide range of environmental conditions and can be used in both indoor and outdoor parts of the system. Its thermal endurance ensures that the switch can operate up to 120°C. Its dust and water resistance is also excellent and can operate in harsh environments.

Conclusion

The TMCGD6ST1040C snap action limit switch is a reliable device for many applications, offering reliable switching performance and repeated operation over a wide range of environmental conditions. Its adjustable operating height and thermal endurance ensure that it can be used in a variety of applications and can provide a reliable switching solution.
