38HM4

Snap action, limit switches are a type of electromechanical switch which are used in a variety of different mechanical applications, including car and industrial machinery. The 38HM4 is a series of industrial switches which has been specially designed to be able to perform these tasks more efficiently. In this article, we will look at the application field and working principle of the 38HM4.

Types of 38HM4 Switch

The 38HM4 switch is available in a number of different types. The most common are the latching, and non-latching types. The latching type is used for momentary action applications such as operating door locks or controlling motion on factory machinery. The non-latching type is used for continual action applications such as maintaining a current or controlling a light. The switches also come in either 2 or 3-pole types, as well as either normally open or normally closed types.

Application Field

The 38HM4 switch is found in a wide range of applications. It can be used in industrial machinery and process control equipment, such as conveyor systems and pumps. It can also be used in motor vehicles, such as cars, tractors and lorries, as a part of the engine control system. In addition, it can be used in household appliances such as washing machines, tumble dryers and dishwashers.

Working Principle

The 38HM4 switch consists of a coil of electrical wire which is connected to a rubber pad. When a voltage is applied to the coil, it causes the rubber pad to move and push on the contacts of the switch. Depending on the type of switch, the effect will either be a momentary action, a continuing current or a light switched on/off. The switch is designed so that the force of the coil is not affected by the amount of current running through it, this means that it will always provide the same amount of switch pressure, no matter how much current is flowing.

Advantages

The 38HM4 switch provides a number of advantages over other types of switches. Firstly, it is very reliable and can handle high levels of current without any issues. Secondly, it is much easier to install and maintain than other types of switches. Finally, it is very economical to use.

Conclusion

The 38HM4 switch is a highly reliable and versatile switch which can be used in a wide variety of applications. It is easy to install, requires minimal maintenance and is very economical to use. This makes it ideal for use in industrial machinery, motor vehicles and household appliances.
