The D4GL-1CFG-A4 is an example of a snap action, limit switch. This type of switch creates a current path through two or more points and then shuts itself off when the limit is reached. The D4GL-1CFG-A4 is typically used when there is a need to monitor the position of a moving object, such as a door, window, or valve.

These switches consist of a housing that contains several contact points, a sensing mechanism, and a release mechanism. The variable being monitored (door position, temperature, voltage, etc.) is connected to the sensing mechanism. When the variable reaches or exceeds a certain limit, the switch is activated as the sensing mechanism releases the switch\'s latch. The contacts then rapidly open and close, transferring an electric current that can be used to trigger other devices or activate an alarm.

The D4GL-1CFG-A4 snap action, limit switch is designed for both indoor and outdoor use and is highly durable. It is self-latching and can withstand variable frequencies, making it perfect for continuous, long-term use. Its contacts are made of high-grade stainless steel and its housing is constructed from high-grade plastic to ensure corrosion resistance. This type of switch is approved by UL and CSA and is compliant with FM standards.

The D4GL-1CFG-A4 can be used in a variety of applications where monitoring and controlling a variable is important. These applications include (but are not limited to) safety control systems, alarm systems, and door, window, or valve position control. Due to its high durability and low contact resistance, it is also used in harsh industrial environments and extreme temperature conditions.

The D4GL-1CFG-A4’s working principle is straightforward and relies on a simple single pole, single throw (SPST) contact configuration. In this configuration, the switch is closed when the sensed variable exceeds or reaches the set limit, and it is opened once the variable falls below the specified limit. This switching action creates a current path between the two contact points which then activates other devices or alarms.

The D4GL-1CFG-A4 snap action, limit switch is a reliable, durable, and versatile device that is perfect for a wide range of applications where monitoring or controlling a variable is necessary. Its self-latching design ensures low contact resistance and its UL and CSA approval ensures safety. Furthermore, its simple SPST contact configuration makes it easy to use, facilitating quick installation and troubleshooting.
