D4JL-2QFA-D7-01

Snap Action, Limit Switches

The D4JL-2QFA-D7-01 is a snap action, limit switch, which is a commonly used electrical device found in many applications. The primary function of this switch is to provide an effective means of controlling electrical circuits and ensuring that power is diverted to its intended application. This type of switch works by physically altering its contact position when pressure is applied to its actuator or when force is applied to its mechanical linkage, allowing for an instantaneous change in state.

Application Field

The D4JL-2QFA-D7-01 switch has a wide range of applications. It is widely used in industrial settings, providing an effective means of controlling a wide range of machinery and processes. It is also used in more consumer-oriented applications, such as vending machines, garage doors, and home alarms. This switch provides a reliable, cost-effective way to control electrical devices.

Working Principle

The D4JL-2QFA-D7-01 works by opening and closing a set of contacts when activated. The contacts are held in place by a spring-loaded actuator, which is moved when pressure is applied to it. When pressure is applied, the actuator is released and the contacts inside the switch open or close, which then allows current to flow through the switch or not. This enables the switch to provide instantaneous switching and control of an electrical circuit.

The D4JL-2QFA-D7-01 is designed to be highly durable and reliable, as it is rated to withstand high pressures and vibrations. Additionally, the internal contact points are made to be highly resistant to corrosion and electrochemical reactions, and can be used in wet or humid environments. This makes the switch suitable for a variety of industrial and consumer applications.
