Snap Action, Limit Switches refer to a switch type that is designed to be used in applications that require the detection of the position of a movable element. Snap action switches, also known as limit switches or snap switches, use an actuator or trigger to detect the position of a mechanically operated object, such as a door or a lever. The switch makes contact within a certain range and opens the contact when the object moves beyond the range. This type of switch consists of a switch body, an actuator, a spring and an electrical contact.

The D4GL-4FFA-A4 snap action limit switch is specifically designed for limited space applications. This switch is equipped with a rotary actuator and a plunger lever which provides reliable service in tough environmental conditions. It is capable of making or breaking an electrical contact with a given current of AC 05 or 12A, or DC 0.3 or 1A, respectively. The rated current of the product is 10A, and the temperature range of the contact is -25°C to +85°C. The maximum switching capacity is 500W and the minimum operating temperature is -25°C.

The D4GL-4FFA-A4 snap action limit switch is used in a wide range of applications where the detection of movement or position of a mechanical element is required. The switch is particularly useful for security systems, industrial control systems, robotics, machine tools, switchgear, and automation applications. The switch can be used to detect the opening or closing of a door, the lifting or lowering of a lever, or the moment when a machine part is activated. The switch can also be used to detect when a limit point has been reached, or when a maximum or minimum position has been attained.

The working principle of the D4GL-4FFA-A4 snap action limit switch is based on the contact between the switch body and the actuator or trigger. The switch body is equipped with a plunger lever and an actuator with a spring. When the trigger or actuator is actuated, it pushes the plunger lever and moves the switch contacts, creating or breaking the electrical connection. The switch is designed to open or close the contact within a certain range. If the movement or position of the object being monitored reaches the limit of the range, the contact will be opened and the electrical connection will be broken.

The D4GL-4FFA-A4 snap action limit switch is a reliable and cost-effective device for various applications. This switch is designed for dependability and long service life, and it is capable of performing in a wide range of temperatures. The switch is also easy to install and maintain, making it the ideal choice for all kinds of security and automation applications.
