D4C-1620

Snap action and limit switches are versatile adjustable switches which are widely used in different electrical and mechanical applications. Among these switches, the D4C-1620 is an extremely interesting and efficient switch, featuring a number of advantages and features compared to other gadgets. This article provides a brief overview of the application field and working principle of the D4C-1620 switch.

Application Field

The D4C-1620 snap action and limit switch has many application fields, but it is particularly useful in situations where an adjustable and making or breaking switching operation is required in order to alter the flow or voltage levels in the system. These switches are typically used in industrial and commercial applications, where they can control a wide range of functions such as motor speed, factory automation, control instruments, and home appliances such as air conditioning and washing machines. The switch can also be used in many other applications where SPDT, DPDT, or double-throw (make-break) switches are required, such as in the development of automation systems and sophisticated machine tools.

Working Principle

The D4C-1620 snap action and limit switch consists of two snap action mechanisms, one of which is adjustable and the other is not. The adjustable mechanism enables the switch to be set within a range of settings, and the non-adjustable mechanism is designed to ensure reliable and repeatable operation at each of the chosen settings.

The actual switching operation is achieved by the action of a spring-loaded plunger which is depressed when the switch is operated. The plunger then bounces back to its original position, or “snaps” into its new position. This snap action causes either a make or break contact in the circuit, thereby allowing the switch to either turn on or off the power to the device.

The D4C-1620 switch is also configured to detect over-travel, meaning that the switch will click into the desired position and then prevent any further action beyond that point. This is a great safety feature which helps to protect the system from damage or overloading.

Conclusion

The D4C-1620 snap action and limit switch is a versatile and cost-effective device which can provide reliable operation in a variety of settings. With adjustable settings, over-travel detection, and a snap action mechanism, it is an ideal choice for applications requiring precision movement and repeatable operations. By understanding the application field and working principle of this switch, users can make an informed decision when choosing the right switch for their needs.
