Snap Action, Limit Switches

The 21CX4HM is a type of snap-action, limit switch. This type of switch offers a reliable solution to limit switch applications requiring shorter switch travel times and increased actuation speeds.

A common application of the 21CX4HM is in machine automation, where it is used to detect the presence or absence of objects in machinery, or to limit the travel of an arm or machine part. The switch contacts are made of silver-nickel, supporting a long-term reliable operation.

The working principle of the switch is that there is an internal spring which provides the force to actuate the switch. When an external force is applied, the internal spring is compressed, activating the switch. When the force is removed, the switch moves back to its original position through the action of the internal spring.

The 21CX4HM offers several advantages when compared to other types of limit switches. It has a high operating speed and can actuate with minimal force. It also provides more reliable switching and is available in both enclosed and open styles. Additionally, it is designed to protect against false operation from the vibration of machinery or other external influences.

The 21CX4HM is a versatile switch that is suitable for many applications. It is designed for applications ranging from industrial machinery to home appliances. It is also used for detecting the position of moving objects, such as in machines with sliding parts. It is also often used as a security switch.

The 21CX4HM is a reliable and economical solution for many applications. It is easy to install and is generally a cost-effective solution. Its simple working principle, combined with its durability, makes it a popular choice for many industries.
