Snap Action, Limit Switches

D4C-6303 is a snap action limit switch with a small and very reliable construction. It is commonly used in various industrial applications to provide overload protection and precise position sensing.

Application Field

The D4C-6303 can be used in a wide range of applications, including control circuit operations, motor overload protection, and sensing operations of movable parts or components. It can also be used to switch on and off lights, motorized pumps and fans, and also in door openers and air compressors.

The switch can be used for both in-line and manual control panels. It can also control multiple circuits with a single switch, allowing for convenient installation and operation. This makes the switch popular in multiple-device applications. The switch also has a built-in safety interlock to prevent accidental power-on. This feature is often used in sensitive applications like medical and industrial equipment.

Working Principle

The switch operates using a snap-action mechanism. When a current is passed through the terminals, it generates an electrical impulse. This impulse is then transferred to a mechanical lever, which snaps into position and opens the contacts. This happens when the predetermined current level is reached, thus allowing the switch to provide overload protection and precise position sensing.

The switch also has an adjustable pressure arm. This arm can be adjusted to control the force of the snap action, thus maintaining a consistent switching threshold. This feature is especially useful in applications where the current level is subject to fluctuations.

The switch is also capable of operating in a variety of positions. It can be mounted horizontally, vertically, or at any angle. This makes it ideal for tight spaces or enclosed spaces, where installing a full-size limit switch is impossible.

In addition to these features, the switch is also capable of operating in high and low temperature environments. It is rated for temperatures between -20°C to +85°C. This makes it an ideal choice for applications that require protection from extreme temperatures.

Conclusion

The D4C-6303 is a reliable, versatile, and economical limit switch. It is capable of providing precise position sensing and overload protection, and it is also capable of operating in a variety of positions. This makes it an ideal choice for a wide range of industrial applications.
