Snap Action, Limit Switches are the most basic, yet an inevitable part of almost any kind of electronic equipment. The D4GL-1FFG-A 4 is an exceptionally durable and reliable snap action limit switch manufactured by Omron. This limit switch offers an extended operational life, superb sensitivity and reliable performance.

The D4GL-1FFG-A4 is available in a wide range of formats, including Normally Closed (NC), Normally Open (NO) and SPDT models. It is also available with multiple switch functions, such as momentary and latching/alternating contacts. This versatility gives the D4GL-1FFG-A4 the adaptability to be used for a variety of applications, such as controlling high voltage or current, operating a mechanical device such as a valve, or in a variety of industrial automation tasks.

The working principle of the D4GL-1FFG-A4 requires no external power source, as it relies upon the physical pressure from an actuating lever on the switch itself. This pressure is responsible for actuating the switch, as well as for keeping it in its active position. The pressure actuates an internal switch contact, which then contacts an electrical coil. The coil subsequently generates a current, which allows the switch to open or close a circuit.

It is important to note that the actuating pressure of the D4GL-1FFG-A4 has to be higher than a certain threshold, determined by the specific switch model. This ensures that short-term electrical irregularities do not actuate the switch. The contact gap of the switch is also critical, as a clean separation between contacts is important for efficient operation.

The D4GL-1FFG-A4 offers high reliability and efficient operation, making it a valuable component for various applications. It can be used for controlling high voltage or current, for controlling a mechanical device such as a valve, or for various industrial automation tasks. The extended life and superior sensitivity of this switch translates into superior performance and extended usage.
