Snap action, limit switches, such as D4GL-1EFG-A4, are widely applied in industrial and commercial applications. Their primary purpose is to detect and measure various physical events, such as temperature, pressure, force, flow, and voltage. They can also be used to detect the position of a moving object such as a door or a valve.

The switch works by sensing a change in a given parameter. When the predetermined value of this parameter is exceeded, the switch is triggered and switches an electrical circuit on or off. This switching action can turn on/off any device requiring power supplied through an electrical connection. The switch can also provide feedback to the system, allowing it to adjust its parameters in order to maintain optimal performance.

The snap-action switch is a mechanical device and consists of two parts; the actuator and the contact mechanism. The actuator is the component that moves when the switch is actuated and it is typically made from metal or plastic. The contact mechanism is the component that completes the circuit when the switch is closed and consists of two contacts, normally open or normally closed, depending on the application. The actuator is held in place by a spring and when the switch is triggered, the actuator is released and moves across the two contacts, causing them to come into contact and close the circuit.

The D4GL-1EFG-A4 switch is designed to operate in temperatures ranging from 0° to 120° Celsius and in wet or damp environments. It is one of the most widely-used snap-action limit switches, due to its reliable performance and wide range of applications. The switch is typically mounted on a resilient material such as rubber and is used to monitor and control a variety of applications, such as:

• Air conditioning systems
• Security systems
• Heating and cooling systems
• Control systems
• Laundry machines

One of the most common applications of the D4GL-1EFG-A4 is its use as an overload protection switch in motor controllers. The switch is normally closed when the motor is off, and its opening when the motor current exceeds a given value acts as a safeguard against overheating. This function helps to prevent potential damage to the motor and provide a longer service life.

The D4GL-1EFG-A4 snap action limit switch is a reliable and versatile solution for industrial and commercial applications. It is capable of detecting and measuring a variety of physical events, as well as controlling electrical circuits. It is also used for overload protection in motor controllers, helping to ensure lasting service life and performance.
