• Snap Action, Limit Switches
• D4SL-4KDG-D Application Field and Working Principle

The D4SL-4KDG-D snap action, limit switch is mainly used in electrical appliances, such as actuators, incandescent lamps, condensers, switches, relays, and thermal elements. These switches are designed to provide less current modes for improved product efficiency and safety, and are offered as OEM/ODM parts for product manufacturers.

The D4SL-4KDG-D snap action, limit switch utilizes two switches with levers attached on the actuator. One is known as the “normally closed” switch and the other the “normally open” switch. This means that when the actuator is pressed in the normal direction, the normally closed switch will open and the normally open switch will close. When the actuator is released, the switch will reset back to its original positions.

The operation of the D4SL-4KDG-D snap action, limit switch is based on the principle of leverage, which is a mechanical property of the switch. The metal lever is connected to a spring-loaded pin and lever assembly, which is designed to yield rapidly when the operating force is applied. This results in an immediate switch action with minimal force needed to actuate the switch.

The D4SL-4KDG-D snap action, limit switch is designed to provide a range of applications, including high-intensity illuminated switches, momentary contact switches, and micro-switches. The contact ratings of the switch range from 0.12A to 5A, depending on the application and environment. The temperature range for the switch is −20°C to +85°C and it can withstand up to 250V for AC or DC currents.

In addition, the D4SL-4KDG-D snap action, limit switch is constructed with high-grade materials for increased reliability and longevity. The dielectric strength of the switch is rated at 500 VAC, and it has a mechanical life of up to 10 million cycles. The switch also has some environmental protection, such as IP67 dustproof and waterproof, and a temperature rating of 55°C.

Overall, the D4SL-4KDG-D snap action, limit switch is an effective and reliable switch that can be used in a variety of applications. The switch’s leverage design ensures a rapid response when actuated, and its wide range of contact ratings and environmentally-protected design provide flexibility and durability. It is an ideal component for the design and manufacture of electrical appliances, switches, and other products.
