GLHA01A4J

Snap Action, Limit Switches are usually mechanical switching components, used to offer precise on/off operations in order to control various machines or systems, sometimes under hazardous and severe conditions. This type of switches are vital components of modern commercial and industrial equipments. GLHA01A4J is a robust example of these devices.GLHA01A4J is essentially an electro-mechanical snap-action limit switch which offers on/off operations under hazardous conditions. It is widely used in industrial controls, HVAC equipment, bottling and food processing machinery, automotive controls and machine tools operations. It is also used to control motors, pumps and other related systems in commercial and industry equipments.GLHA01A4J features a die-cast zinc alloy construction, plus silver-alloy contacts that are resistant to environmental degradation. Furthermore, it is totally liquid tight, ensuring reliable performance in damp and wet environments. In addition, it can operate in temperatures up to +80°C, making it perfect for most industrial applications.GLHA01A4J’s working principle is quite straightforward. It is based on a bimetal disc, which is held in place by a set of springs that allow it to move. When an external force is applied to the disc, its motion is released, causing it to bend. As the bimetal disc bends, its outer edge touches the contact block and causes the circuit to open or close, depending on the disc’s position. This mechanism is what sets the switch’s on/off operation.GLHA01A4J offers a wide variety of options for controlling machinery or systems. It can be used to operate motors and actuators, lighting, alarms and indicators. It can also be used to monitor temperature, pressure and flow.Overall, GLHA01A4J is an extremely reliable and versatile limit switch, designed to meet the requirements of industrial and commercial applications. It is constructed to withstand high temperatures, damp environments and other hazardous conditions. Its simple but robust mechanism makes it ideal for a variety of control applications.
