Snap Action, Limit Switches

Snap action limit switches are mechanical switches that are operated by pressure sensors to control or limit the motion or position of a sliding, rotating, or pressure surface. The switch is triggered when the pressure sensor contacts the pressure surface, causing a snap action by the switch\'s internal components. This type of switch is commonly used in industrial and, to a lesser extent, consumer products.

D4GL-4HFG-A4 Application Field

The D4GL-4HFG-A4 snap action limit switch is designed specifically for use in motion control, security and protective systems, mechanical switches, automotive applications, machinery and dies, and other electromechanical systems. This versatile limit switch is designed for use in various outdoor applications, where the environment may be humid, hot, cold, or otherwise hostile. Furthermore, the IP67 rating of the switch ensures that it is dustproof and waterproof, making it suitable for use in a wide range of applications, from industrial to consumer.

The D4GL-4HFG-A4 is a high-performance limit switch, capable of up to five million switching cycles. Its robust external housing ensures superior durability and resistance to corrosion, and its hermetically sealed contacts remain reliably sealed, even under harsh conditions. The switch comes with a mounting bracket, adjustable trip points ranging from 1.5 to 4.5mm, and a 6.5mm operating stroke. It can be easily mounted in a variety of positions, and is available in a variety of sizes and materials.

D4GL-4HFG-A4 Working Principle

The D4GL-4HFG-A4’s snap action limit switch is operated by a built-in pressure sensor. When the pressure sensor contacts the pressure surface, it triggers a snap action, activating the switch’s internal components and causing them to move. This motion is transmitted through the switch’s contact plates, which are configured so that when they move they make or break the circuit. This, in turn, causes the switch to be either open or closed and to control or limit the action of the surface on which it is mounted.

The D4GL-4HFG-A4 is also designed for flexibility and easy installation. Its multi-pole system enables it to be used in a variety of applications, and its adjustable trip points can be adjusted to meet the specific needs of different applications. Additionally, the robust external housing and hermetically sealed contacts ensure superior resistance to corrosion and make the switch suitable for use in a wide range of applications.
